The old calculate geometry toolĪlthough this tool fulfills most use cases, it falls short in a number of ways. This allows the calculation of area in the coordinate system of the data source or the coordinate system of the data frame in the desired areal units. Most GIS analysts using ArcGIS are taught to calculate polygon areas in ArcMap using the Calculate Geometry tool in the attribute table. It can be exported as a PDF.Calculating polygon areas is one of the most basic geometric operations. When the map looks the way you want it to, go to File > Export Map. Each can be edited by double-clicking once added.ġ4. From the Insert menu, add all the necessary map elements: a legend, north arrow, scale bar, and title. Change the color of the border to No Color.ġ3. Then, right-click in the middle of the map, and go to Properties > Frame. Adjust the size of the data frame so that all of the state is visible. Go to File > Page and Print Setup and change the orientation to Landscape.ġ2. This shows you what the map will look like when printed. To make the city labels stand out more, click on Symbol, then Edit Symbol, then Mask, and click on Halo.ġ1. Still in the Layer Properties menu, go the Labels tab and click the checkbox next to Label features in this layer. Make the picture markers transparent by the selecting the Display tab in Layer Properties and changing the percentage next to Transparent.ġ0. Navigate to the unzipped folder and select p_Sphere_WarmGray.png.ĩ. From the drop-down menu next to Type, select Picture Marker Symbol, which will bring up a file selection menu. Still in the Symbology tab, click on the button under Template, then Edit Symbol. Any kind of image can be substituted for the point symbols. Click on Apply to see how the changes affect the size of the city symbols.Ĩ. Next to Value, select the population variable, and adjust the symbol sizes. Go to Properties > Symbology, and under Quantities, select Graduated Symbols. You can do the same with the Major Cities layer. You can also change the county boundaries click on Symbol above the color patches, select Properties for all Symbols, and change the Outline Color.ħ. Select a new color ramp using the same menu. The will give the ratio of urban residents to total residents per county.Ħ. To give percentages instead, next to Normalization, select TotalPop from the drop-down menu. The colors on the map are based on the total urban population in each county. Right-click on the Counties layer and go to Properties > Symbology. Click on the leftmost button, and you can adjust the orientation of the map manually.ĥ. To adjust the orientation, go to Customize > Toolbars > Data Frame Tools. You’ll notice that the shape of Pennsylvania looks better, but the orientation is unfamiliar. North America in unprojected NAD 1983 coordinate system.Ĥ. North America in North America Lambert Conformal Conic projection. Expand the folders until you see that projection, click on it, and then hit OK.

In the search box, type in “North America Lambert Conformal Conic” and hit enter. We can change the projection of the data frame from the Data Frame Properties menu. You’ll find that it is in the NAD 1983 coordinate system and is not projected, giving it the elongated appearance. To check the coordinate system, go to View > Data Frame Properties > Coordinate System. You’ll notice that the state has a different shape, determined by our map’s coordinate system. Compare Pennsylvania in this map to our example map from PASDA.

To change this, make sure the TOC is in “List by Drawing Order” mode (see circled area below), then drag and drop the Major Cities layer above the Counties layer.ģ. The Major Cities layer, however, does not display because it is underneath the Counties layer. You should see two layers, Counties and Major Cities. Look in the Table of Contents at the left. This should open the map of Pennsylvania counties by urban population.Ģ. Open the unzipped folder and double-click on DesignTutorial.mxd.
