Then in the second stage we saw how this file was sent to a GIS application to create a georeference within a projection.
When I was studying Calculus I, a professor of Asturian origin told us that there are two ways to count a group of cows: counting them or going down to grass level, counting the legs and dividing them by four, and if non-exact data comes out truncating to the nearest whole .
Well, let's see in three steps how to do everything we achieved in those previous moments, with a GIS application. In my case I will do it with manifold, but I guess it must be done with other applications that cost more.
1. Create a new file
To create a new file you make "file / new"
To create a new layer "file / crate / drawing" or with the layers control
Then we assign projection to it, right clicking on the created layer, as we explained in the previous post. I will use UTM Zone 16 North, WGS84
2 Configure the grid
To configure the grid, do "view / graticule", if you want the latitude and longitude mesh. In case you wanted the UTM grid it would be "view / grid"
As what I want is the UTM 16 zone, north, I choose the length -90 to the -84, and since I do not want internal divisions I choose a spacing of 6 degrees.
In the case of latitudes, I am interested in latitude 0 to 72, and that I divide it every 8 degrees. Then you can choose if you want solid lines or shapes or only the crosses at the intersections. By doing Ok, I already have the grid, this is only in view form.
3. Create the grid.
Press the "create" button, and voila.
Moral: Do not do with CAD what you can do with GIS.
Do you want to make it more dense? choose from where to where, the density and press the create button… it must be recognized that GIS programs are limited in terms of vector data construction, but in terms of creating strictly cartographic aspects they are great.
... by chance, how is this done with AutoDesk or ESRI products?
