Seeking datasets that has the degree, minutes and seconds world longitude and latitude

DEAF_PROBERT_68 — Sat, 03 Aug 2019 01:20:13 GMT

I am seeking a GIS datasets that has the longitude and latitude that I really need badly that has the degrees, minutes and seconds .... I am aware that there is 1 degree, 5 degree, 30 degree and 45 degrees.... I do not want them...

Where do I find them ? I have looked around on the internet and didn't find it.... Does ArcGIS Pro come with it ? How about ArcGIS Desktop ?

Yes I know that ArcGIS has its own Longitude and Latitude but I really want the datasets...

coordinates are recorded in decimal degrees in Arc* not DMS. Are you looking for a grid at a fine scale for an area so show DMS on the border of layout? or are you looking at converting DD coordinates to DMS? in a table>\?

Convert Coordinate Notation—Data Management toolbox | ArcGIS Desktop

Oh...yes I mean the arc* . No, I don't want to convert them.

Dan,

No I am not crazy about that but I need the dataset because I am doing georeference and the scanned map has it there...that is why I asked about it...

Maybe just make your own: Make Grids And Graticules Layer—Topographic Production toolbox | ArcGIS Desktop

That is interesting but I think it will take me some time to make this work... Have you tried this in the past, friend ?

Yes, with ArcMap, but I haven't tried the tool in Pro. I assume it is very similar. You could also just use Create Fishnet—Data Management toolbox | ArcGIS Desktop, which doesn't generate as much in terms of output, but maybe a single grid is all you need.

Well I found out, I myself did not realized that the Degrees, Minutes, Seconads datasets, will have almost 4 billion polygons worldwide...

So with that said, I will only need a small region area is what I need and not the whold world...

I will follow what other suggest me to do is create a Fishnet or make my own Grids and Gratticules Layer...

Thank you.

I marked this question as "assumed answered" since it pertained to downloading a pre-existing data set. If you have questions on using either of the tools suggested, you can start a new question.

Sure I will. I will just have to go to YouTube and check them out ...

The only thing I am retaing is the 1 degree graticule I have here from the Natural Earth site... Which is good ...just need the seconds...

Let me know if you are able to see it or not but here is the picture of what I am talking about...

This depends on the coordinate system used by the map. If you are using ArcGIS, open Arccatlog and right click on the map. Click on Properties and drop down on the coordinate system. Is it in the UTM for the picture is unclear if you work on it and you want first Geometric correction and selection of appropriate projection

In ArcMap, use the "Grid" icon by right-clicking on the "layer" and selecting Properties

maybe it was just marked off in 1 degree increments, meaning that the seconds would be 0.

If you are georeferencing old maps marked in longitude/latitude, you could just use an online DMS - DD converter to do the conversion for your control points.

Thanks.. I have never thought about that....good idea... I will try and do this method and see..

BTW, I tried what Joshua Bixby's suggesting to do this tool : Make Grids And Graticules Layer—Topographic Production toolbox | ArcGIS Desktop

It is a good tool only if you are working on a small area but for a large area might be too much....though also it takes a lot of time and it took me a while to understand this tool works...

I was able to get it done what I wanted....but I will do your suggestion and compare with the other tool.

Phew... I have been working very hard and tired and got what I wanted...so here is the picture..

I still have not georeferenc the old picture yet....so the begins now !
