GIS STEPS – EXPORT DIGITAL INFORMATION 
1. STEP 
To do the task we need to use both ArcMap and 
GlobalMapper. 
ArcGIS 
 Open the software 
 “Open data” command 
o Open the document 
that you want, in this 
case we need to open a 
map the shows the 
location that we want 
the digital information 
o For us open the 
“Admin8.shp” file to 
import the map of 
Hungary 
For the task we want to extract the digital 
information of Debrecen to work more on it, 
but the map that we open have all the citys in 
Hungary, wich we don’t need, so is better to 
work only with the Debrecen area, to do that: 
 “Selection” ABA 
o Selection by attributes 
 “NAME” double click 
 = 
 “Debrecen” 
 To see the 
names go to 
open feauteres 
And select your 
choice 
 
o Press “Verify” to see if 
the equation that you 
put will running. 
o If its ok, press OK/Apply 
After this you will see Debrecen select in Blue 
on the MAP, this means your command works 
and now is showing your select attribute. 
Now that you select, you only want to work 
with the attribute that you chose. To do that 
you need to extract what you select from the 
hole map. 
 Export the Select ATT 
o With the right bottom go to the 
layer of Debrecen 
o “data” 
o “export data” 
 Selected features: that 
mean will export your 
shape of Debrecen 
 Save on your folder 
After extract the shape you don’t need the hole 
map to remain open, so remove it for a better 
operation. Now we need to import the shape of 
Debrecen on the GlobalMapper. 
 2. STEP 
With the GlobalMapper we will get the digital 
information for the shape that we’re working. 
 GLOBAL MAPPER 
 Zoom in to Hungary 
 “Open Data files” command 
 
 
 “Open Data files” command 
o Open the shape that 
you create 
To extract the information you need to export 
the file. 
 On the layer (debrecen) 
o Right bottom 
o “select” 
 On the layer of the MAP 
(ASTER GDEM) 
o Right bottom 
o “layer” 
o “Export” 
 Ok 
 GeoTIFF 
 On the first aba 
you chose the 
“Generate PRJ 
file” 
 On the 3th aba 
you select the 
“crop to select 
areas features” 
 Ok -> save 
On this point you already have the digital 
information about your shape. To keep working 
on this you need to open it on the Arc Map.
