You can't directly in one step, as far as I know. Raster_columns and raster_overviews are both views. This was done by design to prevent mismatches between constraints, meta data and actual data. You can see the definition of these views if you look in the file rtpostgis.sql that comes in the contrib/postgis/ folder of the postgres directory. All of this ...

I think what you need is to geo-reference your data. Here's a link: http://docs.qgis.org/2.2/en/docs/user_manual/plugins/plugins_georeferencer.html and I'm sure ARCgis has something similar...as does Python+gdal, and any legitimate GIS program. The basic problem is that your coordinate system is totally non standard so doing a projection change will not ...

An oblique mercator projection might solve your issue. See this Q&A for details: Using customized Coordinate System for Archaeological site data

Under Settings -> Options, CRS tab, enable Prompt for CRS for new layers. Then you will be asked explicitely for the CRS, which should be the same as you georeferenced to in Arcgis. You might get a datum shift of up to 100m, as this is not stored by Arcgis. But QGIS has bundled the shift with the common projection definitions.

Since your data is already in UTM 34N projection, all you have to do is reproject it to your local CRS. You can do this with gdalwarp (even in batch mode for a whole folder), or inside QGIS with Raster -> Projections -> Warp . ARCGIS should offer similar tools. So no need for georeferencing manually.

So, georeferencing panel in ArcMap provides 2 options - update georeferencing and rectify. Update georeferencing creates jgwx, pnwx, tfwx extensions and this can't be opened in geoserver. Solution is to rectify all images, which creates pgw-like extensions. To define a world file's projection in geoserver you have to make exact copy of projection definition ...

The Map has mostly remarks in French, so I would suggest to use a French coordinate system, and not Everest (who was British). The French used coordinate systems with a prime meridian based at Paris, so EPSG:4821 Voirol 1879 (Paris) is a good start-off. With that, the 100° meridian is hitting the Malaysian coast near Kota Baru, as in your map: You can ...

To begin with I would recommend you read this tutorial on georeferencing in QGIS http://docs.qgis.org/2.2/en/docs/training_manual/forestry/map_georeferencing.html Yes you can georeference this map. I would recommend you use a good quality flat scan of the map if possible. Avoid a crease running through the image. Accurate georeferencing depends on the ...

Assuming you have saved the output of your GCP points, can you compare the values in this file with the auto-generated script? I've noticed that the script rounds values; I wonder if this could be introducing a source of error.

I guess you want to append the data, but not merging it, am I right? You can do this by applying the following SQL query in the CartoDB Editor: INSERT INTO table1name (column1, column2, column3) SELECT column1, column2, column3 FROM table2name This will insert all your rows from table 2 into table 1. Notice that you need to use conveniently the column ...

Use listgeo http://www.remotesensing.org/geotiff/listgeo.html for saving the georeferencing info into a file and write it back to edited file with geotifcp http://www.remotesensing.org/geotiff/geotifcp.html.

You can use the spatial adjustment method in ARC GIS. Once you add into arc Map, you need to make it editable than after spatial adjustment option is enable.And you also import your control point Spatial Adjustment->Link->Open Link....... For more details please refer Spatial Adjustment section of ESRI help

The original PNG apparently has your monitor's display color profile embedded in it, which is non-gray-balanced. Since QGIS cannot accurately interpret the icc profile's whitepoint (see the warning in the second line of your gdal output,) it clipping the red channel to 0 with that visible result. If you have access to Photoshop, open the PNG, use ...
