Standardization in Archeology for Territorial Cadaster Purposes Guilherme Butter Scofano*, Francisco Henrique de Oliveira*, Sonia Elisete Rampazzo**, Mariane Alves Dal Santo* * Universidade do Estado de Santa Catarina – UDESC Programa de Pós-Graduação em Planejamento Territorial e Desenvolvimento Socioambiental/Laboratório de Geoprocessamento GeoLab ** Universidade do Sul de Santa Catarina (UNISUL) Abstract This scientific paper is about the relationship between cartography and the Brazilian archeology, mainly in its institutional aspects, and aims to contribute to the debate about the need for standardization of cartographic products and the data generated by geotechnologies, as regards the representation and registration of archaeological sites. From this bias, the research identifies the need of compatibility between the cadastral management systems developed by IPHAN and those developed by the municipal bodies of urban management. Both systems rely on the integration of descriptive textual data and geospatial information, generated by inventorial and cartographic surveys. The results obtained were the proposition of an archaeological cadastral system based on legal premises of the Multipurpose Territorial Cadaster (MTC) and the territorial demarcation techniques defined by the Brazilian National Standards Organization (ABNT). Keywords: Multipurpose Territorial Cadaster; Archaeology; Cartographic Standardization. 1. Introduction In Brazil, it is recent the adoption, by government bodies, of technical standards for the generation and sharing of geospatial data. Sectors of most representativeness, such as the environmental, mining and politicalterritorial have consistent georeferenced databases, which are open to the public and cover a wide range of subjects. In the cultivation sector, however, the same scenario is not verified. Although the sector works with information and references directly linked to the issue of spatiality, the geographic products officially adopted as a government strategic management tools are scarce. In the archeology field, linked to the culture sector in Brazil, the deficiency is evidenced in the treatment of material patrimony, consisting of archaeological sites distributed throughout the national territory. The absence of geospatial products hampers the archaeological patrimony management routines which involve the supervision and monitoring of excavations, research and potentially harmful works to the sites and prehistoric materials. The lack of geographic data also compromises the dialogue between the institutions responsible for the archaeological properties and the civil society, in their economic and legal aspects. The evolution of the archaeological data treatment in Brazil depends, invariably, on the insertion of land registry techniques, aimed at standardization of registration procedures and sharing of spatial information. In this sense, it is emphasized the possibility of inserting the archaeological theme to the practices of Multipurpose Territorial Cadaster (MTC) as a strategy for integration between municipal and federal agencies. The research developed seeks to correlate the archaeological issue in Brazil and the intrinsic precepts to MTC, in order to suggest a model of spatial data generation and sharing, based on the concept of "cadastre parcel of archaeological content”. 2. The Archaeological Issue in Brazil 2.1 Legal Aspects The Brazil Federal Constitution of 1988, through its article 216, defines the existing archaeological sites in Brazil as elements belonging to the national cultural patrimony,''bearers of reference to the identity, to the action, to the memory of the different groups of Brazilian society''. The same document requires the public administration to be responsible for managing the official documentary products related to the archaeological patrimony, as well as the duty to apply penalties to those who cause harm and threats to assets. The Magna Carta explains in an indelible way the importance of the archaeological patrimony for the identity construction process of the national territory groups. However, the archaeological theme is covered in two others documents previous to the 1980 decade. The first one refers to the Decree - Law Nº 25, of November 30th, 1937. The decree, in its article 1, considers as cultural patrimony the assets of exceptional archaeological value, "whose conservation is in the public interest”. The decree also provides the creation of a Book, where items of archaeological nature must be registered, along with the categories of ethnographic and landscape assets. Once registered in the Book, the property inscribed shall be protected by the Government, so that any actions that lead to changes in the asset must be previously authorized by the responsible agencies. The second document previous to the Federal Constitution is shown as the main Brazilian law aimed at archaeological theme. Dubbed as Archaeology Law, the Law Nº 3.924 of July 26, 1961, primarily deals with issues relating to the protection and management of the Brazilian archaeological patrimony. The law defines that all archaeological asset (Figure 1) identified in the Brazilian territory should remain under guard of the Union, and the Federal Government is responsible to control the forms of exploitation, research and preservation of the archaeological sites locations. The document links the regency of the assets management procedures to the already extinct Board of National Historical and Artistic Patrimony, which currently receives the nickname of National Historical and Artistic Patrimony Institute (IPHAN). Figure 1: Archaeological asset “sambaqui type” surrounding by urban area. Source: GRUPEP/Arqueologia (2012) Also according to the Archaeology Law, the Government is responsible for maintaining a record of existing archaeological sites throughout the country, in which information concerning each of the identified materials sets should be recorded. In addition, the law provides that, in the event of the discovery of archaeological assets in a particular property, the property owner is required to ensure the conservation of the identified asset, until the Public Power manifests. It occurs that, after more than 50 years since the law was created, few legal advances were conquered. Although, during this period, the IPHAN has issued decrees with guidelines for the achievement of researches1 and linked the archaeological theme to environmental licensing processes2, the legal regulation to generate the record of material assets remained neglected. The following topic details the current situation of the cadastral system of Brazilian archaeological patrimony, concerning cartographic aspects and descriptive data. 2.2 Cadastral aspects Given the determinations of the Archaeology Law, the IPHAN maintains the so-called National Register of Archaeological Sites (CNSA), in which are registered just over 21,000 archaeological sites, spread across all Brazilian States. The registration, which is open to the society through the IPHAN 3 virtual portal, offers registration forms relating to their respective archaeological sites. The registration forms follow a model developed by IPHAN, and are filled by the archaeologists responsible for recording the identified sites. The filling, however, does not occur with the desired level of detail, in a way that the forms are inserted into the cadastral system with practically no information. It is often to be provided only the site identifier code and your city 1 Portaria IPHAN nº 07, December 1, 1988. 2 Portaria IPHAN nº 230, December 17, 2002. 3 http://portal.iphan.gov.br/portal/montaPaginaSGPA.do of origin, without further elaboration on the characteristics of the registered asset. If the set of archaeological sites registration forms contains serious shortcomings, the situation is aggravated when the cartographic question is analyzed. The institute does not provide or mentions, in its virtual portal, spatial data representing the Brazilian archaeological sites, and that are accessible to the community. The institute does not have a national rule that defines the minimum requirements for the delivery of cartographic products by archeology professionals, in charge of spatial record of the researched archaeological assets. What is possible to verify are specific actions, performed by technicians of some States IPHAN’s Superintendences, in order to establish technical requirements mapping of the sites, consistent with the officially established cartographic standards. These actions, however, do not guarantee the production of a quality spatial data throughout Brazil, but only for the States where IPHAN's superintendences define a minimum technical regulation. Despite the critical context described, it is emphasized that the Institute has been working for the improvement of its database, by creating the so-called Knowledge and Management Integrated System (SICG). The system's access has not yet been granted to the public, but academic articles4 and lectures given by professionals of IPHAN5 report that the system will have a module for geographical information processing via internet, allowing the integration and standardization of georeferenced spatial files. 2.3 Socioeconomic aspects The consequences of the deficiency in the Brazilian archaeological cadastral system are proven in different sectors of public administration, especially in the context of municipal governance. Without proper identification of the (geo)location of archaeological sites, the city expands on areas of prohibitive occupation. The Figure 2 illustrates the abovementioned; it shows a house built on a hill of shells formed by human occupation of shellmound type in the municipality of Laguna, State of Santa Catarina. 4 (Da Guia et al. 2015).

Source: IPHAN SC (2012) Aside from the physical damage to property, which reaches irremediably the identity construction elements of the population itself, the unfamiliarity towards the archaeological patrimony has effects on the processes of income generation by municipal governments. Tax calculations on the land, such as the Urban Land and Building Tax (IPTU), the Rural Land Tax (ITR) and the Tax on Property Transmission (ITBI) are developed based on the opportunities of occupation of each property. Given the identification of archaeological sites, the occupancy rates are reviewed, reflecting on the amounts collected by the city. There are other aspects affected, in a major or minor extent, by the absence of archaeological records. The changes of architectural standards, or even the embargo of construction projects due to insufficient archaeological studies, variations of municipal real estate’s dynamics, or difficulties in formulating politics that encourage tourism and patrimony education are examples of damages caused directly or indirectly by deficiencies in the management of archaeological assets. If the archaeological question is felt more clearly in the municipal scale, it is based on it that we propose the methods for improvement of the Brazilian archaeological cadastral model. The following topic discusses the Multipurpose Territorial Cadastre, whose technical regulations suits to demands from the cultural patrimony departments. 3. The Multipurpose Territorial Cadastre in Brazil 3.1 Conceptualization The Brazilian Multipurpose Territorial Cadastre is defined by Erba et al. (2005, page 18) as "a systematic public registry of property from one jurisdiction contemplated in its three fundamental aspects: The legal, the geometric and economic”. Formalized in the country through Ordinance Nº. 511, of December 7th, 2009, the MTC is intended primarily to the Brazilian municipalities, and has the minimum territorial unit called the "cadastral parcel”. According to Article 2 of the same document, the cadastral parcel is "defined as an adjacent part of the land’s surface with singular legal regime", from which is possible to model the other territorial units of a city, as lots, plots and public roads, and others. To ensure proper identification and individualization of parcels, each unit shall be provided at the time of your registration, with a single and stable code, from which the descriptive data entered into the database maintained by municipal organs are linked. These descriptive data contains varied textual information, relating to the physical characteristics of the parcel, to the control points adopted for its measurement, to the forms of land use and the owner data. In addition to the descriptive information, the MTC also has the spatial representation of the references used for the field survey, as well as the polygon formed by the cadastral parcel registered. Figure 2, taken from Hasenack (2013), shows a field survey, where is referenced the necessary elements to identify a real estate. Figure 2 - Example of cadastral survey Source: Hasenack (2013) The set of spatial data from a city originates to the so called “Cadastral Map”, which compiles the products from the entire mapping collection performed in the city. The multipurpose character assigned to the parcelling registration is due to the possibilities of the data generated to suit different users and different purposes. Since each cadastral parcel is assigned to a legal system and a specific form of land use, the access to the database of a municipal MTC allows you to perform several spatial analyses, encompassing legal, economic, environmental and social issues, and others. 3.2 Technical Parameters The effective application of the MTC principles depends on the execution of technical procedures focused on cartographic representation and on the descriptive record of the parcelling registered elements. Therefore, the Ordinance Nº. 511/09 provides that the geometric survey of the parcels should be referenced by the so-called Brazilian Geodetic System, and supported by the network of local landmarks maintained by municipal governments. In addition, the ordinance establishes that the cartography produced for record purposes shall obey the standards set by the National Spatial Data Infrastructure (Infraestrutura Nacional de Dados Espaciais - INDE), and the rules of the National Commission of Cartography (Comissão Nacional de Cartografia - CONCAR). Thus, it is expected that all cartographic record designed to parcelling representation respects the same performance criteria, enabling the consolidation of the MTC in all Brazilian territory. Among the technical guidance, it is given the obligatory generation of surveys based on topographic procedures, whose parameters are set by the Brazilian Association of Technical Standards (Associação Brasileira de Normas Técnicas - ABNT). Among the standards developed by ABNT, it is highlighted the documents NBR 13133 and the NBR 14166, that conceptualize and describe each necessary step to Cadastral Land Parcelling survey, and provides convenient technical indexes to every terrain measurement mode. The contribution of technical standards for the creation of legal instruments aimed at specific segments of the land register is emphasized. The main example comes from the National Institute for Colonization and Agrarian Reform (do Instituto Nacional de Colonização e Reforma Agrária - INCRA), responsible for Ordinance nº. 578/2010, and which approves the Technical Standard for Rural Property Georeferencing. The rule has specific methods and technical indexes for demarcation and registration of agricultural prop- erties, which preserve the stipulated criteria of the MTC by Ordinance 511/09. Assuming the possibility of adequacy of technical standards that support the MTC to different cadastral contexts, it is presented in the next section, a proposal for a cadastral model focused on the record of archaeological sites. The proposal aims to suggest a system capable of integrating the developer’s agents and consumers of cartographic and descriptive materials of archaeological content. 3.3 Territorial Registration of Archaeological Content Parcels Considering the cadastral parcel as the basic unit of territorial organization, and considering the importance, in different institutional scales, of identifying and custody of the archeological occurrence sites, the inclusion of the archaeological record to the methodological model of MTC is interpreted as an integration process between the federal and local agents. Therefore, it is necessary that the registration of the sites follows the parcelling precepts prescribed by law. So, we suggest, in the logical of MTC cadastre, the demarcation of what we call "archaeological content portion”. This territorial category would apply to an area of different legal regime, occupied by archaeological sites or located in the immediate surroundings of a site. In order to identify a portion of archaeological content, it would be necessary to prove the occurrence of at least one of the following elements: Archeological site fully inserted on a property; Archeological site partially inserted on a property; Archeological site's surrounding area fully inserted on a property; or Archeological site's surrounding area partially inserted on a property. The categories are illustrated in Figure 3. Figure 3 - Categories of archaeological content plots Source: Scofano (2013) Once confirmed the archaeological occurrence, the demarcated portion would count with the tutelage of the Union, so that the forms of exploitation and the tax calculations for the defined area would be revised. With the Land Parcelling registration of the entire city, the Registration Letter (Deed), which production is obligatory for cities adherent to the MTC, would present the delimitation of all archaeological set identified inside the municipal territory. The process of generation and availability of registration data, however, must follow a well-directed flow, which determines clearly each one of the production stages, validation and data transfer. It is necessary, at first, that the archaeological site discovered is delimited on the basis of surveying procedures regulated by the Brazilian Technical Standards and adapted to the necessary particularities for the preservation of materials deposited on the ground. The site should have its characteristics described by an archeology professional. The descriptive document must include the physical landmarks deployed to demarcate the parcel, of coordinates measured by enabled geometers. In the next step, the developed products must be forwarded by the archaeologist to the IPHAN, in charge of the site's official registration in the federal system. The official information are transferred posteriorly to the municipality, which is responsible for the registration of the parcel of archaeological content. Finally, the data referring to the municipal Land Parcelling records are sent by the city to the IPHAN, so that both institutions share the same cartographic and descriptive documents. Steps necessary for publicizing geospatial data with archaeological content • • IPHAN Homologation data Site of registration Transfer data • • • • Publicity of the data Entering information in IPHAN database Archaeologist Recognition of the site Surveying of the site and surroundings Generate of spatial data Generate data attributes Transfer of the Site Cadastre Data • • City Hall Homologation data Parcel Cadastre Entering information in the municipal database Figure 4 - Necessary stages to publishing geospatial data of archaeological content. Source: Scofano (2013) With the recording of archaeological content parcels, the municipalities are able to not only spatially delimit the areas of occurrence of the sites, but to identify the owners of the property where archaeological assets are located, assisting in supervision actions and legal protection to the local cultural patrimony. At a federal level, the assimilation of the concept of share of archaeological content as an official instrument of territorial demarcation warrants to the IPHAN the subsidies to require the archaeologists and municipalities to generate cartographic and descriptive products within a standardized registration system and appropriate to the Brazilian technical standards. It also allows the generation of a database covering the whole country, and its information can be available through virtual platforms open to society. Publicity of the data 4. Conclusion Although Brazil has serious shortcomings in its archaeological patrimony protection model, it is highlighted the possibility of improvement from the incorporation of technical and methodological procedures arising from the Multipurpose Territorial Cadastre. On the other hand, the MTC, recently incorporated into the Brazilian legal reality, does not contemplate the archaeological matter in a clearly way, therefore, it becomes responsibility of agents for the assets management, especially the IPHAN and local governments, the task of matching the logic of MTC to the demands of cartographic and descriptive record of prehistoric material assets. In our interpretation, the preservation of the archaeological patrimony in Brazil depends on the consolidation of a system that integrates the Union, cities, archaeologists and geometers. Based on the concept of the cadastral parcel of archaeological content, the system must be focused to the territorial demarcation, generation of cartographic and descriptive content, sharing and standardization of data, and availability of information to civil society. 5.
