I wanna see the extent of difference in geocoding results performed by ArcGis and Texas A&M Geocoding Services. I have 500 geocoded addresses using Texas A&M Geocoding Services in Latitude/Longitude NAD1983. Now I want to convert it to (UTM_1983_Zone_18N). So that I can calculate the distance between two UTMs using excel. Second geocoded addresses in (UTM_1983_Zone_18N) was created with ArcGis 10.2.
Any idea how to make this conversion?
Solved! Go to Solution.
I am still confused as to what you have. If the coordinate systems properties is correct (GCS NAD83 aka a decimal degree file with a NAD83 datum) you are ready to Project it as described. If you examined its coordinate system and it is unknown, then you use the Define Projection tool in Arctoolbox to define it as the GCS NAD83 format, then you use the Project tool in the same toolbox. If it is some other file format, then you will have to elaborate
why not use the Project tool in Data Managemen, Projections and Transformations, Project to get the data into a projected UTM file, or set the data frame to that projection to just see what they look like but not change the coordinates. The first option is the best if you want to calculate distance.
Thanks Dan.
Do I have to specify the column Texas A&M Geocoding Services in
Latitude/Longitude NAD1983 in the attribute table? so that project tool
can convert this actual two columns to new UTM_1983_Zone_18N columns?
Btw, I am a beginner in ArcGIS.
You want a feature class or shapefile which has been produced via geocoding which you have specified as having a Geographic Coordinate system NAD83. Once a file's coordinate system is known, then it can be projected. To find out what it is check it in ArcCatalog or right click on the layer, and select properties then examine it there.
Thanks
I can use Convert Coordinate Notation/Data Management, correct? I have
just figured out my current coordinate system properties.

In my shapefile I have:
1. Latitude and Longitude created by Texas A&M Geocoding Services in
NAD1983
and
2. Point_X and Point_Y created using NY Geocoding service by ArcGis in
(UTM_1983_Zone_18N) .
I am trying to end up with x and y coordinates for two points both in a UTM
coordinate system. So that i can calculate the distance between two points
in Excel using formula like: meters= sqrt((x1-x2)^{2)+(y1-y2)}2).
This is what i get for properties.

Thanks and just to update you on the way of conversion: Calculate geometry
function worked out perfect for this case. I also use your suggestion to
use "project".
