If you're seeking generic terms, which are independent of the shape of the coordinate reference surface (planar or spheroidal) for coordinate axes, you're out of luck. For planar reference surfaces, the terms are northings and eastings (or in very rare cases, southings and westings). For spheroidal reference surfaces, the terms are latitude and longitude ...

No, because UTM coordinates are repeated in each zone. If the data was localized--only covered the eastern and western parts of two zones, you might be able to do it because you could segregate the values into the two zones. If you had 539594, 9071398 and 493840, 9198483 are these in the same zone or in zones 31 and 32 or 10 and 11?

I recommend you to have a look at the webpage epsg.io. There you can search also for regions to see which EPSG-codes are common for these regions. As you have written in your profile that you are from Sweden, I guess the coordinates are from Sweden,too. The best match i found so far was EPSG 3006 but i guess you flipped the x and y -values, is that possible? ...

My suggestion is to go with your "if we have to" concept at the end, and not hard-code those into the UI. Instead, make the Coordinate system a combo-box at the top of that part of the UI, and then generate whatever the axes are from the user's selection in that combo-box. If that is really an input box and the CRS terms are going to change fairly often ...

Expanding on mkennedy's comment, and translating generic map terms to proj.4 parameters: Projection - Lambert Conical Orthomorphic → +proj=lcc Ellipsoid: Bessel 1841 → +ellps=bessel False Easting : 700000 → +x_0=700000 False Northing : 600000 → +y_0=600000 Central Meridian : 14.0° ...

I have a new stack exchange account and don't have a reputation high enough to comment on the "Uncaught TypeError: Failed to execute 'putImageData' on 'CanvasRenderingContext2D': float parameter 3 is non-finite." error. This occurs because you have the lat and the long inputs backwards. map.getView().setCenter(ol.proj.transform([lat, long], 'EPSG:4326', ...

You have to consider that QGIS uses the NADCON datum shift grid, while other software might use a 3- or 7-parameter Molodensky transformation, or no transformation at all. The shift grid is internally used in +datum=NAD27, but when the grid file is not included in the software, it might just do nothing. You will get a small shift anyway because the ...

@Michael Miles-Stimson was on track w/ his first comment. since your ArcGIS Tiled Map Service defines its own projection using WKT (as opposed to WKID), you need to use an identical projection definition in your code to indicate to the JSAPI that the point you are passing is in the same coordinate system as the map. check out a working jsbin here another ...

The central meridian of the UTM systems is at 93°W +/- 6° and has a value of 500000m in the local system. So you have to look up those central meridians and see which aligns with your UTM grid. The next central meridian will be about 300 km away, and appear bended in the chosen UTM projection.

I'm going to put this as an answer, but I'm making several assumptions so this may not be the 'right' answer! This will prove whether or not the values are ED1950 UTM 33 North but with the leading digits stripped off. Delete any coordinate reference system from the problematic shapefile. A very easy way to do this is to delete (or rename) the .prj file. ...

You should be able to do this by using the Project Raster (Data Management) tool to transform your DEM from a Geographic Coordinate System in decimal degrees to a Projected Coordinate System in meters.

Try this : import com.vividsolutions.jts.geom.Coordinate; import javax.measure.unit.NonSI; import org.jscience.geography.coordinates.LatLong; import org.jscience.geography.coordinates.UTM; import org.jscience.geography.coordinates.crs.ReferenceEllipsoid; This method makes the conversion in JAVA and return a Coordinate. Is easy to obtain X and Y from ...

An old Shapefile projected in GK3 although with a Transverse Mercator as Projection System was found and deleted. After restarting the PC Computer, all Settings for GK3 are now consistent across the different zones.

I can't figure out how this is occurring. I stepped back in time, and I can't find an occurrence where 31467 ever used Transverse Mercator for the projection name. It would be quite unusual because I usually copy and paste definitions when setting up a set of zones like this, so I would expect all zones to have Transverse Mercator. You're correct that at ...

After making some assumptions, here's a possible prj file for the definition that you gave. The assumptions are: GeoCRS is NAD 1983 False easting is 1872000.0 meters (assuming the origin values are given in meters) False northing is -828000.0 meters (this is the one that I feel most unsure about) (2) and (3) are based on the statement that the 0,0 ...

This seems to be a known bug in GDAL working in the background of QGIS about different ways of definition for LCC 1-SP and 2-SP projections: See https://github.com/mapbox/node-srs/issues/1 http://lists.osgeo.org/pipermail/gdal-dev/2011-May/028728.html http://trac.osgeo.org/gdal/ticket/2072 Adding ESRI:: in a gdalwarp command line as described should ...

The different software applications are either Not applying any datum transformation Applying different transformations One trick when comparing different software applications and there's a datum transformation involved is to run each step separately if possible. In this case, convert from WGS 1984 to NAD 1927 first. If the values are not changed, or ...

The DEM tiles are already projected if they are in NAD 1983 UTM Zone 17/18N. From what I understand, a Mosaic Dataset IS able to handle multiple projections: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//009t0000000n000000 just search this page for "different projections" and you will find a brief paragraph explaining this. You will, ...

I solve my problem with editing database and inverse Y field : create 2 copy of original table(contain personal data). sort 1st copy of table with Z,X,Y ACE and add a newID. sort 2nd copy of table with Z,X ACE and Y DESC and add a newID. update Y filed of 1st table with Y of 2nd table where newID=newID. now i have a table (1st copy) same as original ...
