A lot more people know how to use Photoshop, and you also donât have to send all the GIS data along with your file.
Here is a brief guide for creating such a map.
The basic idea is, in ArcView, to export each layer separately with a transparent background. The second idea is to group some layers together in this process to avoid to have too many messy layers in the Photoshop file that would be hard to understand and manage for a non-specialist user. In the following guidelines weâre going to follow an easy example. This example is a map of the Tibetan counties of TAR, Sichuan, Qinghai, Gansu and Yunnan, along with the surrounding countries:
For such a map the layering in ArcView is as follow:
As you can see, there are 7 layers. In order to handle the labels more easily, they have been transformed as annotations. There are here two groups of annotations: the names of the countries, and the numbering of the counties. Finally, there is also the legend (including the north arrow and the scale), which is also going to be handled separately. Before to begin the export of the layers, double-click on âLayersâ on the left at the top of the different layers in order to bring the settings of the dataframe. There, on the tab âFrameâ set the background color as transparent (ânoneâ in other words in ArcView language).
To export the first layer, you have to turn all the annotation groups off, and move the legend + north arrow + scale out of the frame. In our example, the base layer is going to be the colors of the countries. Turn all the layers off, except the base layer which is âadm0â. Here is a good example as for when one can group sveral layers in a single one. Depending on how your data is structured, sometime you need two layers where you could have only one. Here, in order to depict the contested areas with a neutral greyish color, we had to add a layer on top of âadm0â which is called âadm0 â contested territoriesâ. The lambda user doesnât need to have these two layers, as they both participate for the same basic layer. So in this first export we are going to leave these two layers turned on, as in the picture below:
In the âExport Mapâ dialog box (to be found in âFileâ menu), set the image as a png, and in the second tab set the background color as ânoneâ.
Proceed like that for all the different layers, without forgetting to group those that can be grouped together. Each export will be a different layer in Photoshop. In our example I could have added the white Tibetan areas with the base layer, but for a particular reason I wanted to let the option to the person to who this map was intended to be able to turn on and off this layer â so I made it a separate layer.
When you export only lines, you have something like that:
Setting the background as ânoneâ both in the dataframe properties and in the âExport Mapâ dialogue box is very important, otherwise it will screw all the white areas and lines of your map. One example is the white polygon for the Tibetan areas. Although it looks dumb like that when youâre going to export it:
If you set the transparencies right you will have this resulting image:
For the labels, you have to turn all the layers off. You can, if itâs adapted for the needs of the person for who the map is intended, group all the annotation groups together. In this example the person needed to be able to turn the numbering of the counties off. So we created two layers: one for the labels of the countries, another one for the labels of the counties.
Finally, you have to export the legend + North arrow + scale:
As a result, we have for this map 9 layers: 6 for the shapefiles, 2 for the labels, and one for the legend.
You should now have something like in the image a little further down.
At the end, merge them with the âBackgroundâ layer.
