サマリー
Esri Defense Mapping cartographic production tool that creates and smooths contours from an input raster.
使用法
Set the Map Scale parameter to the scale at which your cartographic products will be printed. The tool uses this parameter to improve contour display in output products.
This tool requires specific fields in Out Contour Features. Out Contour Features should be a Defense Mapping data model feature class.
This tool uses the following process to generate contours:
- Create contours by executing the Spatial Analyst Contour tool.
- Smooth contours by applying a Defense Mapping-specific algorithm.
- Calculate contour fields that pertain to Defense Mapping data models.
構文
CreateContours(Input_Raster, Map_Scale, Base_Contour, Contour_Interval, Index_Interval, Include_Zero_Contour, Out_Contour_Features, Contour_Subtype, {Input_Area_of_Interest}, {Raster_Elevation_Units}, {Contour_Elevation_Units}, {Resample_Raster})
パラメーター | 説明 | データ タイプ |
Input_Raster [Input_Raster,...] | A list of rasters from which contours will be created. | Raster Layer |
Map_Scale | The scale at which the cartographic product will be printed. The tool optimizes cartographic display by setting a minimum feature length based on this scale.
| String |
Base_Contour | Base contour value. Contours are generated above and below this value to cover the entire value range of the input raster. Setting this value to 5 and the contour interval to 10 will produce contour lines at 5, 15, 25, -5, -15, and so on. The default is zero. | Double |
Contour_Interval | The interval, or distance, between contour lines. This can be any positive number. | Double |
Index_Interval | Indicates the index contour interval. | Double |
Include_Zero_Contour | Indicates if the tool will create a zero contour. A zero contour represents sea level. Zero contours, when generated along a coastline, may be created inside a water body. Specify INCLUDE_ZERO_CONTOUR if you will generate contours on land areas that are at or below sea level.
| Boolean |
Out_Contour_Features | A feature layer from an existing Defense Mapping feature class. This tool appends contours to this feature class and returns a feature layer. | Feature Layer |
Contour_Subtype | A subtype in Out_Contour_Features to which contours will be written. | String |
Input_Area_of_Interest (オプション) | An area of interest (AOI) that is contained in a raster and is used to clip the raster before creating contours. A buffer is created before clipping the raster and results in larger output contours that extend beyond the selected AOI. | Feature Layer |
Raster_Elevation_Units [Raster_Elevation_Units,...] (オプション) | The measurement units for elevation values in the Input Raster parameter.
| String |
Contour_Elevation_Units [Contour_Elevation_Units,...] (オプション) | Contour elevation units will be created with the same elevation units as raster values unless specified to use different units, such as feet instead of meters.
| String |
Resample_Raster (オプション) | Indicates if the tool will resample the Input_Raster before creating contours.
| Boolean |
コードのサンプル
CreateContours example (Python window)
The following Python window script demonstrates how to use the CreateContours tool.
# set gp environment
arcpy.env.workspace="C:/data"
# variables for tool
rasters="elevation.tif"
mapScale="1:12500"
baseContour=0
contourInterval=10
# output feature class must exist
outContours="mgcp.gdb/mgcp/contours"
noIdx="NO_INDEX_CONTOURS"
contourSubtype="FCSubtype"
# execute the tool
arcpy.CreateContours_defense(rasters,mapScale,baseContour,contourInterval,outContours,contourSubtype)
