In order not to lose momentum, more than Alzheimer's now and then betrays us, here I leave part of the free consultancy I was giving to some guys from Mexico, who keep using Geographics.
1. The data
It has a map, which contains four sectors, then each block has Boundaries and centroids. The centroid has link To the database, in the table apples, And also contains the sector name in the column Cve_Sec.
So in this case, I want to thematize the apples, based on the sector number. I will clarify this issue first, because it was necessary because the link to the database was from the centroids and not from the shapes.
- Create shapes. If it is not visible, we activate the Geographics toolbar, in the menu Tools> Geographics> Geographics. To generate the shapes, we turn off all levels, leaving only the level of apple and centroids, we make a fence And choose the icon called Create shapes.
It requires a level that is free where the shapes will be stored.
- Move links to shapes. For this, we turn off the level of apple boundary, and leave only the level of shapes and centroids. We make a fence And select the fourth icon called Associate Linkages, Indicating Centroid -> Shape And clicking on the screen.
- Review Links. The signal that everything is fine, is that when using the command Review Attributes, The data that had the centroid was lifted.
2. How to Thematize
To thematically select Data base> thematic resimbolization.
A window appears, in which you have to configure, to the right if you want the theming to be only visual or saved in a map layer. Also if we want it from the whole file, or from a Fence. Then on the buttons on the left, with Add, if we want to ask questions via queries Specific.
Select the button Car, To indicate that we expect the program to automatically search for categories. There we select the table Apples, And the column Cve_sec, we indicate that the classes are unique, filling, base color and level at which each layer goes. Then when doing Ok, We can choose another color again, because the ones it shows are a bit ugly.
And that's all, see that by indicating Go, And click on the screen, are themed apples based on sectors.
3. How to put the legend
This is done Settings> Legend, and the option of two points is chosen in the panel or the size is defined in the unit of measurement that we are working, in this case I will use 100 x 100 meters.
With Bentley Map, that another wave, but much more kind.
