#Get mean value of raster in polygon in arcgis 10.3 archive
Lab3 is a Winzip archive that contains the data that are needed for this tutorial and exercise 3. NOTE: Before beginning the tutorial, please make sure you map the geography server and copy the file named Lab3 to your personal server folder. Exploring the different ways in which data are generalized. Selecting and modifying appropriate symbology for different data types. Learning to use the symbology window in ArcMap. The objectives of this tutorial include: 1. Also, different symbolization strategies are used for vector and raster data. Some are better portrayed by points or lines. Of course, not all features are symbolized using areas. Such data are usually generalized into a smaller number of categories in which each is symbolized by a different fill or color. By contrast, a map showing population density uses ratio scale data.
Such data are often nominal in scale (trees, developed, water, etc.) and only require that you pick an appropriate fill pattern or color for each type. For example, you may be asked to make a simple land cover map. You need to select the correct symbology for the data type and, if necessary, select an appropriate generalization. Remember that the use of appropriate map symbology (points, lines, area fills, color, etc.) and map design determines how effective a map is as a graphic communication tool. Although not specifically a map-making or cartographic program, ArcGIS does feature a wide range of cartographic functions and symbology. 1 Tutorial 3 - Map Symbology in ArcGIS Introduction ArcGIS provides many ways to display and analyze map features.
