hello a greeting to the entire community of
@utopian-io, he writes @geoestacion and wanted to show him my work regarding the application of remote sensing, by using a software called Global mapper, for a lot of maybe it is known, well this tool is very important for all the work I do In my professional area, through this software you can execute various practices related to the area of cartography, in my first presentation here, which I have called practice, is called photo-reading, the interpretation that we can give to satellite images, in this material shown below can be seen step by step of the use of global mapper software for the use of this mapping work.

PRACTICE # 1 FOTOLECTURE

We open the Global Mapper Software:

1

We look for the image with the file option, then we open the image:

2

After getting the image, we give the option Manually Rectify :

3

Once selected the option to rectify, we go to option and select
"Add Control points when eating point"

4

The indicated projection is selected, in this case it is the Cassini Solder Projection, the other parameters shown are left the same.

5

After accepting the terms, we proceed to select each of the points to georeference them.

6

Once all the points are georeferenced, we proceed to select each of the layers of the vertices, so that this way you can save the update of the points, then select Ok.

7

After the image has the 4 control points established, the practice is carried out with the selected image, in this sense, this practice was done with photo 020.

8

Using the Global Mapper's editing tools, we proceed to identify the natural and artificial elements. Elements of type polygons, lines and points will be used to identify them. In this last capture one can observe, as each element, both natural and artificial, was photointerpreted.

9

I hope friends that my presentation is interesting for all of you, later I will publish other types of practices that can be done with this type of software, who says goodbye to you @geoestacion.

I recommend first of all that you download the Software: Global Mapper.
