Using the Spatial Analyst IDW (Inverse Distance Weighted) tool an ArcGlS user interpolates a point feature class to a raster. The user notices that some high point values near the edge of the feature class seem to have a dramatic effect on the output.
This occurs even in areas that are far from the high edge values
Which two parameters should the user consider changing in the IDW tool? (Choose two)
An ArcGIS user is making a map and needs to symbolize cliff and escarpment features above contour features. How can the features be ordered correctly if they are all in the same layer?
A layer tiding simple symbology is causing slow drawing performance at a scale where analysis needs to be conducted. Only certain features from this layer are necessary in order for analysis to be completed by the ArcGlS user
What can the user do to increase drawing performance?
An ArcGiS user wants to dynamically generalize a line using the Douglas-Peucker algorithm. Which geometric effect should be used to achieve this?
An ArcGlS user maintains a street signpost database with measure in terms of two route feature classes: distance from the nearest school and distance along the street.
If the two feature classes are created from the same source line feature class, which geoprocessing tool will support calculating one event from the other?
