Geographic Information Systems (GIS) Expectations
Inception Phase
Draft Version
The purpose of this document is to outline the GIS functionality necessary to fulfill the
requirements of the Shellfish Water Monitoring IBEAM module. It is hoped that the document
will be useful in preparing a workable database schema using both the traditional IBEAM
database structure and ARC-SDE.
1. Monitoring Stations
a. Given latitude of longitude of monitoring station location, return the following:
i. FIPS code for county in which monitoring station is located
ii. Identifier of DSHA in which monitoring station is located
iii. Identifier of sub-area in which monitoring station is located
1. Classification of monitoring station is implicit in (iii). Monitoring
station classification will be used extensively. A completely
dynamic implementation, then, is undesirable as its effect on
module performance is likely to be significant.
b. Given latitude and longitude coordinates of monitoring station location, display
map showing the monitoring station’s location.
2. Sampling Run
a. [Extension of 1b] Display map showing monitoring station locations for all
monitoring stations associated with a given sampling run.
3. Rain Gauges
a. Given latitude and longitude of rain gauge, return the following:
i. ID of DSHA in which rain gauge is located
ii. FIPS code for county in which rain gauge is located.
b. Display map showing location of rain gauge.
4. DSHAs
a. Import list of DSHAs
b. FIPS county code(s) for counties contained in each DSHA.
c. Calculate total acreage, acreage open, and acreage closed by DSHA, by county,
and by total managed area.
d. Display a map of a given DSHA.
5. Sub-areas
a. Import list of Sub-areas contained within each DSHA
b. Sub-area ID
