1. Extract
1.1 Clip
- The Clip Features can be points, lines,
and polygons, depending on the Input
Features type.
The Output Feature Class will contain all
the attributes of the Input Features.
-
01_SUTcampus
Select shp >> BinPoint.shp, Road.shp, Building.shp and LandZone.shp
BinPoint.shp
Select polygon of landzone
that you want to clip
1. Extract
1.2 Split
- The Split Features dataset must be
polygons.
The Split Field data type must be
character. Its unique values form the
names of output feature classes.
-
The feature attribute table of each
output feature class contains the same
fields as the Input Features attribute
table.
-
1.2 Split
Select shp >> Building.shp and LandZone.shp
Proximity
2.1 Buffer
Buffers can be created inside or outside of
polygons.
2.2 Multiple ring buffer
Creates multiple buffers at specified
distances around the input features. These
buffers can optionally be merged and
dissolved using the buffer distance values to
create non-overlapping buffers.
2.1 Buffer
Select shp >> BinPoint.shp, Road.shp and Building.shp
Output dissolve type : none
Output dissolve type : ALL
2.2 Multiple ring buffer
3. Overlay
3.1 Union
All input feature classes and feature
layers must have polygon geometry.
3.1 Union
Select shp >> buffer_binpoint_10m.shp
and buffer_road_10m.shp
Look at the attribute
3.2 Intersect
Input Features must be simple
features: point, multipoint, line, or
polygon. They cannot be complex
features such as annotation features,
dimension features, or network
features.
3.2 Intersect
Select shp >> buffer_binpoint_10m.shp
and buffer_road_10m.shp
3.3 Identity
- Input Features can be point,
multipoint, line, or polygon. The inputs
cannot be annotation features,
dimension features, or network
features.
- Identity Features must be polygons
or have the same geometry type as
the Input Features.
3.3 Identity
Select shp >> buffer_road_10m.shp and LandZone.shp
3.4 Update
- The Input Features must be of type
polygon.
- The input feature class will not be
modified by this tool. The results of the
tool will be written to a new feature
class.
- The Update Features must be polygon.
- The input feature class and update
feature class field names must match.
- If the update feature class is missing one
(or many) of the fields that are present in
the input feature class, the input feature
class field value for the missing fields will
be removed from the output feature
class.
3.4 Update
Select shp >> buffer_road_10m.shp
and LandZone.shp
3.5 Dissolve
- This tool is used to create a
simplified coverage from one that is
more complex. Although the input
coverage may contain information
concerning many feature attributes,
the output coverage contains
information only about the dissolve
item.
- The merging of polygons with this
tool is the counterpart of intersecting
polygons in overlays. Dissolve will
remove the boundaries.
- The output coverage cannot already
exist.
3.5 Dissolve
00_Administrative korat >> select
>> polbndry polygon.shp
3.6 Merge
- Use this tool to combine datasets from
multiple sources into a new, single
output dataset. All input datasets must
be of the same type. For example,
several point feature classes can be
merged, or several tables can be
merged, but a line feature class cannot
be merged with a polygon feature class.
- Combines multiple input datasets of
the same data type into a single, new
output dataset. This tool can combine
point, line, or polygon feature classes or
tables
