ArcGIS Mapping Tips Series (3)-Make the map more stereoscopic

by Li Yuanxiang

In the previous chapters, we have introduced a variety of map effects, such as luminous effects, hillshade effects, vegetation fill effects, and so on, all of these effects are just a combination of various techniques and techniques to use, make full use of imagination to fill those pale map. In this chapter, we want to achieve a very great goal, is to give a very flat map of a "breast" and "liposuction" plastic surgery, let it become exquisite embossed. Let's take a look at a flat map.

is a map of the administrative divisions, belong to very common maps, even with the color, the display effect is very general. In order to satisfy the public's aesthetic requirements, the author decided to pick up the scalpel and give it a plastic surgery. What we'd most like to see is a map like this.

Here's a look at some of the actions you've done. First, this data is a good distance of the "buffer" analysis, the Earth people know how to do. But what we do is an internal buffer, which is almost the usual trick of my surgeon. Select an appropriate distance and do a buffer analysis.

After buffering the results below, you can see the obvious and the original Basemap constitutes a gap, in fact, we do the inner buffer is the need for this space.

Next, we do a "Euclidean distance" analysis for this data buffer, for what? is to expose a little-known secret. This requires the tool to find the Euclidean distance within the spatial tool. Do not think that this tool is generally used in cost and statistical calculation, in fact, its role is very large. Select the inner buffered layer as the input parameter, and enter other appropriate parameters (refer again to the appropriate word, what is appropriate, is to try a few times, try to the right place, like picking clothes)

Click "OK" to eventually generate Euclidean distance. The resulting result is a bit ugly, as shown in. However, the ugly map to become beautiful is the author's consistent purpose.

However, the ugly map to become beautiful is the author's consistent purpose. Next, the results of this Euclidean distance are cropped using the data management--grid--raster processing--cropping tool. Cutting needs to pay attention to certain matters, processing range Select the most primitive administrative division layer, key section select "Crop geometry with input features", such as

By clipping, the outline of the European distance is completely sketched.

The result of this Heibuliuqiu is a grid data. Until one step, everything we do is dog poop and we don't know what we're doing. However, in this step, it is all the key steps have been completed. The key is that the middle of these boundaries at the edge of the space to empty some of the lower gray space. The next step is the time to play the imagination, remember "Daming Lake's Summer rain lotus?" "Oh, no, I remember the previous chapter. ArcGIS Cartographic Technique Series (2) Terrain rendering? Yes, that's it. We can draw on the previous experience to make a hillshade effect from this raster data. Not only the terrain can do oh, all the raster data is OK, the tool never rejects the parameters that meet the criteria.

If the effect is very good, then the azimuth and height angle of two parameters are used appropriate data. This is done by default.

At this step, the beauty of the embryo is almost carved, you can put on her clothes. is to overlay the original layer and adjust the transparency of the administrative division layer. Other unrelated layers can be removed.

Finally, the veil of mystery is revealed, and the figure of its "exquisite floating convex" can be seen. This is a beautiful map.

If this effect is not enough, you can continue to configure the representation to refine it, such as

Summarize:

This stereoscopic still uses the powerful analytic tools of ArcGIS to make auxiliary cartography by very ingenious generating some auxiliary data. Its data principle is the same as the vegetation filling effect, from scratch; its display is inspired by the terrain rendering. Everything here is old bottles of new wine, re-packaging can be a new one. Therefore, the same sentence, cartographic technology is limited, cartographic skills are unlimited, the imagination is without boundaries.
