Data types for geoprocessing tool parameters
Script example
# Convert input data to weighted point data and render
# Import system modules
import arcgisscripting, sys, string, os
# Create the Geoprocessor object
gp = arcgisscripting.create()
# Local variables...
workspace = "c:/project93/data"
input = "coffeestar.shp"
input_weighted = "star_weight.shp"
weighted_rendered = "weighted_rendered.lyr"
try:
# Set the workspace (to avoid having to type in the full path to the data every time)
gp.Workspace = workspace
# Process: Collect Events with Rendering...
gp.CollectEventsRendered_stats(input, input_weighted, weighted_rendered)
except:
# If an error occurred while running a tool, print the messages
print gp.GetMessages()
Model
| Element | Explanation |
| Collect Events |
Finds all features at the same location and counts them. Creates a new feature class that has a feature at this location with the count as an attribute. |
| Count Rendering |
Renders features with a hot to cold color scheme based on an input count field. |
