I have been struggling with how to find the row number and column number for particular points in any raster map.

My raster details:

columns and rows:  720 360 
cell size (0.5, 0.5)

How can I know the row number and column number by pointing the cursor at any location in the map?

It looks like you could add the information to the attribute table:

HowTo: Locate the column and row of a point within a raster

using the field calculator or Spatial Analyst

NO,this if you have something to add.My case is how to display x and y – Jonsson Oct 4 '12 at 15:45

@WafaAlyaari The method that the answer describes is a way to display the X and Y. It embeds that information into each row by adding x and y fields. – Michael Todd Oct 4 '12 at 16:28

You need to specify which tool you are using. There are a lot which can provide you such kind of information and more reg raster maps. QGIS is pretty good GUI and qgis raster query

there is also another tools such as GRASS GIS,iview(OSSIM) etc which provides you the information.

Thanks for this. So I have to learn QGIS.is there a way through Arcgis 9.3 – Jonsson Oct 4 '12 at 13:36

the tag is arcgis so I would assume he is using arcgis... – Craig Oct 4 '12 at 14:40
however,where is the number of pixcl and lines in your attached map – Jonsson Oct 4 '12 at 14:50
sorry its for qgis. ossim iview provides row,col number and pixel value. – rashad Oct 4 '12 at 15:04
I have downloaded QGIS and I have my map append how can I know the number of pixel and lins – Jonsson Oct 4 '12 at 15:08

ok. try this. http://download.osgeo.org/ossim/installers/windows/ossimplanet-installer-1.8.3.exe which gives you a iview tool as i told earlier

iview

line and sample highlighted are row and column

Hope this helps

It seems that there is no solution within GIS. Because even in QGIS you see the pixel and line and then you do not see the latitude and longitude or latitude coordinates. – Jonsson Oct 5 '12 at 14:37
No I disagree. Because providing such features are not a difficult task. Some users(individual/company) need to ask for such features in open source projects. Maybe its of less priority. I dont like to make you install another tool. But I had seen another tool which provide the functionality called "ILWIS". I guess QGIS hasn't concentrated more on the imagery/raster data. OSSIM works mainly for imagery. so the pixel(x,y) is important. and ILWIS has raster operations such as classification,clustering etc. so it also has the feature – rashad Oct 6 '12 at 16:42
maybe ArcGIS also has it because it has more raster processing algorithms. – rashad Oct 6 '12 at 16:43
