If you look at the picture below, you'll see your Shapefile is actually being displayed on the map. But it's not being projected to your map's reference system. Your Shapefile has EPSG:4326 (as you can see here) and your map has EPSG:900913. So, in your ol_simple.js file, change line: var outProj = new OpenLayers.Projection('EPSG:3857'); by: var ...

Could you use the "Create Feature Class from XY table" instead? This can be done with a right click on the table in the Catalog window in ArcMap or Catalog.

This is an old quarrel between ESRI and GDAL about projection names. If you create a project with layers in EPSG:2272, an additional .qpj file will be created that contains the EPSG code number. Once you have done this, QGIS will always look into that file and not into the .prj from ESRI (without EPSG number). In QGIS, you can safely use Rightclick -> ...

From ArcGIS is the crs ESRI WKT version (SpatialReference.org, EPSG.io) From QGIS is the official crs OGC WKT version (EPSG.io) These ESRI WKT definitions are not all supported by other GIS or libraries (depending of your version of GDAL)

First, you should not trust Google Earth alone. Using QGIS, you might try the OpenLayers plugin with Openstreetmap data to see if that has the same offset. You might try to set the projection to EPSG:22195 Campo Inchauspe / Argentina 5 which has a datum offset to the current POSGAR transformation. Don't use reprojection, because the data will stay on the ...

There should be essentially no difference. I don't know quite how to clearly explain this, but when re-projecting, you are in fact re-sampling at the same time, even if your cellsize were to remain the same. In order to project, the projection algorithm has to know where to 'place' the data, i.e., it has to have a location to project each cell value to, ...

You could assign a projection to your map in the platform you are working in. For example, you could first try to assign a UTM Zone 11 North projection and overlay the map with a base map (e.g. Google Layer) and see whether the features of your map align with the features of the base layer. If not, assign UTM Zone 12, and so on.

I am guessing your basemap is in Web Mercator? Handle the graphics and convert their geometry to Web Mercator individually arrayUtil.forEach(graphicsLayer.graphics, function(g){ var geom = esri.geometry.geographicToWebMercator(g.geom); g.setGeometry(geom); });

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.

You have to distinguish between project CRS and layer CRS. If you use Google/Bing background, the project CRS must be set to EPSG:3857. The other layers you add can have a different CRS. On-the-fly-reprojection will align these layers, even if they have a different projection than the background. What you should not do is to use Set CRS for Layer. This ...

I wish to thank @mkennedy for his useful help. I am posting a reply with some details just in case someone will jump here in the future. I do not know why, but the shapefiles they provided were without .prj file, yet they infomed me that the coordinate system used was a stripped version of ED1950,UTM-zone33N. I managed to fix the problem by the following ...

If the data is all in the same projection just delete all the .prjs and .qpjs Then add them into qgis or ESRI and check they all line up

As of Jan 2015, I'm not aware of any open source implementation that fully supports every possible option in geopackage. The spec is authoritative (but likely to be updated) for implementation, so if you want to (or really don't want to, but still have to) write your own map engine, work from that. Look for a sane subset/profile, rather than trying to do it ...

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. ...

If you don't want to use an equal-area reprojection, you might get acceptable accuracy by calculating an approximation with the field calculator. It will calculate polygon areas as DecimalDegrees^2 with the $area field, but you would need to correct it for the decreasing scale of the longitudinal measurements. Entering an expression of: ...

the jsapi is smart enough to be able to reproject WGS84 geometries added to the map on the fly internally and display them in web mercator {wkid:3857} applications. check out esri/geometry/webMercatorUtils for a look at clientside methods that help you do the same on your own. if you need to reproject between other coordinate systems you'll either need ...

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.

You've caught a lot of the differences. Esri never adopted the WKIDs for the map projection algorithms or parameter names so those are all different. We didn't agree with how carefully defined the parameter definitions are. Ours are more generalized. We don't support TOWGS84 nor some of the newer keywords. When we compare strings (names), we ignore the ...

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 ...

ArcGis attempts to project your data when doing a buffer in inappropriate units, this works for smaller datasets, it cannot do this if the points are dispersed all over the globe as it can't pick one to suit the whole dataset. You are going to need to do each point (or cluster) individually, projecting to an appropriate projected coordinate system. For ...

I don't have such a list, but going through the GDAL code will guide you: https://svn.osgeo.org/gdal/trunk/autotest/osr/osr_esri.py https://trac.osgeo.org/gdal/browser/trunk/gdal/ogr/ogr_srs_esri.cpp https://trac.osgeo.org/gdal/browser/trunk/gdal/ogr/ogr_srs_esri_names.h https://trac.osgeo.org/gdal/browser/trunk/gdal/ogr/ogrspatialreference.cpp

I suggest (as Vince) to put the center of your custom projection in the middle of the study area at 168 W 59 N. The following projections might give best results: +proj=laea +lat_0=59 +lon_0=-168 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs +proj=aea +lat_1=53 +lat_2=65 +lat_0=59 +lon_0=-168 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs +proj=tmerc ...

Depending on which version you have, you can add translation/rotation/scale information to a CAD layer via its layer property page in ArcMap. There's an option to enable an extra transformation. Another possibility is to incorporate the LDP scale factor (LDPSF) into the existing coordinate reference system. If it's Transverse Mercator-based, multiply the ...

If you can not save to a different CRS, your data is probably not in WGS84 EPSG:4326. The coordinate system is designed in degrees, therefore limited to x/y= +/- 180/90. If your coordinates have bigger values, they are in a projected CRS using meters or feet as units. Unfortunately, WGS84 Pseudo mercator (used by Google and Openstreetmap) and WGS84 UTM xy ...

From QGIS you can select 'Save As' and specify the output coordinate system. Right click on the layer, select save as and change the coordinate system: It is important to set CRS to 'Selected CRS' and not to 'Project CRS'; in a previous post on the subject it was determined that there is a bug in using the project CRS. However, when you make the shape ...
