An ArcGlS user is given a populated geodatabase thai contains a few highly accurate feature classes and a few feature classes that are less accurate.
When designing a geodatabase topology, which coordinate rank should be assigned to feature classes of less accuracy when compared with feature classes of higher accuracy?
An ArcGIS user creates a map showing the level of human Impact on the natural landscape. Major habitat types are shown with unique colors, and the level of disturbance for each habitat Is shown with a graduated symbol.
What is this type of map symbology?
AnArcGIS user is tasked with editing a layer containing a large number of features, using another layer thatis in a different coordinate a system as reference. The user adds the layers in ArcMap and starts an editsession. A warning message about editing data in a different coordinate system is displayed.
What is the most efficient way to edit the data to avoid potential distortion in the data?
An ArcGlS user adds an ESRl World Imagery service from ArcGlS Online to an empty Arc Map document.
The user then adds a polygon feature class representing national parks to the map.
The spatial reference of the national parks feature class is:
• Datum North American Datum 1927
• Linear units meters
• Protection Albers equal area
The user intends to digitize new national park boundaries using the features in the imagery.
What should the user avoid doing in the edit session?
An ArcGlS user decides to use labels in a map document because the annotation appears pixelated as the user zooms from the reference scale
What Is a potential effect of this decision?
An ArcGIS user is tasked with publishing an image service out of a collection of rectified satellite imagery. Building the Image service definition results In a rotated dataset with large areas of NoData on the comers. The ArcGIS user needs to recompute the footprints to remove the large areas of NoData on the edges. Which method of recomputing footprints accomplishes this?
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?
