I believe that is a component of a shapefile, so I'm surprised at the error you are receiving. By any chance do you have any other files with the same name as the .cpg one, but with different extensions (i.e. .shp, .shx,.dbf, etc)?

.cpg—An optional file that can be used to specify the code page for identifying the character set to be used.

Hi!! Thanks you for your answer

I have two files:

Grid_CR_suppressed_WB.cpg

Grid_CR_suppressed_WB.shp

I can see the shapefile normally...but this no has many information (only have an column "ID" with values of 2x2kmX365Y280). And the file .cpg, can't open the file ...

I think that these file are related and that the .cpg will give me more information or that this file is a satellite image.

Thanks for your help

yes, I have seen this thread before in a similar incarnation, I have never gotten an answer as to the source etc. Figuring out whether it is a codepage file is as simple as opening it in notepad or notepad++ If it is a oneliner with UTF in it then it is a codepage file

Hi Dan

If, I open the shapefile with Notepad this only display information of ID (column) with 3326 rows (this column only have information with a little description 1x1kmX760Y240 or 2x2kmX760Y241.. etc, etc). This description is poligonos of areas that should bring socio-economic information.

And the .cpg file in Notepad only indicates "UTF-8"

Thank you

the *.cpg file is a codepage file... you don't open it... arcmap uses it for language related stuff

the *.shp file is the geometry portion of a shapefile ... you don't open it either...

a shapefile needs ... as a minimum ... a *.dbf, *.shp, *.shx as a minimum, where the * is the filename. A shapefile may contain many other files like a *.prj (projection file), *.sbx, *.sbn etc etc etc.

Shapefiles are added to ArcMap using the Add data button.

If you are missing one of the three necessary files... you will have some free time on your hands, since there is nothing you can do about it, all 3 are needed as a minimum.

I have the files: dbf, prj, resource AUTOCAD and shx... all these all these the charge once in the GIS.. they appear from the GIS as Grid_CR_suppressed_WB.shp ( I open it and only shows me the ID column))

Then I see the raster Grid_CR_suppressed_WB.cpg and this cant open from my GIS

Thanks

Again, it is a codepage file... it provides language support ... generally is has a UTF-8 in the line

UTF-8 - Wikipedia, the free encyclopedia

But I could have all my text in Greek, Latin, Arabic or other alphanumerics character sets, and you would need to have the codepage file in order to see the true characters.

So, I need one file more... the "codepage file"?.

A silly question more..which its the appearance of this file to load it from ARCMAP or just need is make click on the geometry and this show me the information automatically.

Thanks Dan.

you don't even need the codepage file... you don't need to open it, you don't even have to look at it, it won't show you anything that you can't already see

HernandezAstorga — Fri, 01 Apr 2016 17:13:53 GMT

Dan, these are my files

The dta files were produced on a different date so they could be from any source, they could be data files in either binary or ascii format

https://desktop.arcgis.com/en/arcmap/latest/manage-data/raster-and-images/supported-raster-dataset-file-formats.htm is the list of raster file formats, so I can't see it.

Our library lists ones we use GIS Formats | MacOdrum Library

but dta? and not dat? If you can open it up in a text editor, then it may be data you can join to the shapefile. I would ask the people where you got it from, since you didn't create it, they may have the necessary metadata to help

So Dan, with these files I cant see the information. Your suggestion is.. that they send me again the complete files

DanPatterson_Retired — Fri, 01 Apr 2016 18:07:49 GMT

Yes... with some explanation as to what they are and how to use them
