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 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?
Refer to the exhibit. Questions and Answers PDF 23/34 The ArcGIS user is given data for the Arctic, and is asked to perform various types of analysis using the dat a. The data extends from the North Pole south to 55 degrees North Latitude Data layers may contain points lines, or polygons and include ice surveys from NOAA depth contours; continental margins, locations of known and suspected oil reserves, endangered sp ecies habitat and territorial boundaries for nations having Arctic coastline. An ArcGIS user is asked to calculate the distance a cruise ship will travel through open water, departing from Nome, Alaska, with stops at Point Barrow Alaska Churchill Manitoba St John's Newfoundland and ending in Bar Harbor Maine. On the basis of these calculations the cruise ship line will determine fuel requirements and travel time. Which map projection yields the most accurate results for this distance calculation?
A raster dataset called rasterl.tif contains many pixels with values of NoData. Which map algebra expression changes NoData values to 0 (zero) in the output raster dataset while leaving all other pixel values the same?
An ArcGIS user has overlayed two polygon feature classes to produce an output feature class with the following user -managed attributes: • Soil_Code • Aquifer_Type • SuitabilityClass Which geoprocessing operation should the user perform in order to combine the polygons of the output feature class based on the Suitability_Class attribute value?
An ArcGlS user receives two shapefiles that are defined with the same projection and represent features in the same study are a. When they are displayed together in ArcMap. the difference of their locations in coordinate space is so large that they are barely visible when viewed at their full extent. How can the user determine whether the projections of the shapefi les are correctly defined?
