How to add spatial reference ESRI:102100 as a custom CRS to Geoserver?

How to add spatial reference ESRI:102100 as a custom CRS to Geoserver?


I've been struggling with this for over a week. I'm using the ArcGIS Javascript API to create a basic map application, and I'm trying to add a WMS layer from my geoserver to this application. The problem is that the basic map app I'm working with is using an ESRI basemap with spatial reference ESRI:102100. My wms layer is using spatial reference EPSG:4326. See my other question for more details about this: ArcGIS Javascript API - How to define spatial reference for WMS layer?

When I run my application I get this error:

  Error occurred decoding the espg code urn:x-ogc:def:crs:EPSG:102100 No code "EPSG:102100" from authority "European Petroleum Survey Group" found for object of type "IdentifiedObject". 

I tried to add ESRI:102100 as a custom CRS to my Geoserver (by editing the epsg.properties file), but it adds it as EPSG:102100 which is not a valid epsg code according to the error message I'm getting. Anybody know how to get Geoserver to recognize ESRI:102100? Or, anybody know how to properly define a wms layer from a geoserver in ArcGIS Javascript API?


So I finally found the solution to this problem. You have to override the spatialReferences array of the WMSLayer object right before adding it to the map.

wmsLayer.spatialReferences[0] = 3857; map.addLayers([wmsLayer]);

This worked with a layer using EPSG:3857 and another layer using ESPG:4326.

1. Types of grids

Square or rectangular grids are frequently used for purposes such as translating spatial information expressed in Cartesian coordinates latitude and longitude into and out of the grid system. Such grids may or may not be aligned with the grid lines of latitude and longitude for example, Marsden Squares, World Meteorological Organization squares, c-squares and others are aligned, while Universal Transverse Mercator coordinate system and various national grid based systems such as the British national grid reference system are not. In general, these grids fall into two classes, those that are equal angle ", that have cell sizes that are constant in degrees of latitude and longitude but are unequal in area particularly with varying latitude, or those that are equal area ", that have cell sizes that are constant in distance on the ground e.g. 100 km, 10 km but not in degrees of longitude, in particular.

A commonly used triangular grid is the "Quaternary Triangular Mesh" QTM, which was developed by Geoffrey Dutton in the early 1980s. It eventually resulted in a thesis entitled "A Hierarchical Coordinate System for Geoprocessing and Cartography" that was published in 1999. This grid was also employed as the basis of the rotatable globe that forms part of the Microsoft Encarta product.

Hexagonal grids may also be used. In general, triangular and hexagonal grids are constructed so as to better approach the goals of equal-area or nearly so plus more seamless coverage across the poles, which tends to be a problem area for square or rectangular grids since in these cases, the cell width diminishes to nothing at the pole and those cells adjacent to the pole then become 3- rather than 4-sided. Criteria for optimal discrete global gridding have been proposed by both Goodchild and Kimerling in which equal area cells are deemed of prime importance.

Quadtrees are a specialised form of grid in which the resolution of the grid is varied according to the nature and complexity of the data to be fitted, across the 2-d space. Polar grids utilize the polar coordinate system, using circles of a prescribed radius that are divided into sectors of a certain angle. Coordinates are given as the radius and angle from the center of the grid.
