comment how to move point(points) by a vector in Qgis
Please use the edit button beneath your question to revise it with those details. Including a picture may also be useful to supplement the text. Once edited your question will be re-opened.

comment how to move point(points) by a vector in Qgis
Would you be able to edit your question to include more details of what you have tried and where you are stuck, please? For example, what do mean by "moving the point by a vector"? Do you perhaps mean moving it by an angle and distance? Have you looked at the QGIS documentation to see what advice is offered about different ways you can move points/features?

comment How to know which parameter is dependent in GWR?
What have you tried so far? I suspect that you will need to edit your question to provide considerably more detail about what you have tried and where you are stuck before potential answerers will be attracted to your question.

comment OpenLayers preview problem?
@MarkC My apologies for just rejecting your addition of a qgis tag - I had interpreted "open layer" earlier as being "OpenLayers" and now I'm not sure whether this involves both QGIS and OpenLayers or just QGIS. I think we will need to await Fauzano editing his question to clarify, but in the meantime I don't think I can undo the edit rejection so I'll just add the QGIS tag back.

comment Creating single feature to represent group of individual features, based on location and #, using ArcGIS Desktop?
I recommend reviewing earlier Q&As here which are tagged arcgis-desktop and clustering to see if one or more of them has something in common with what you are trying to do. Also, adding a picture to your question may make it much easier for potential answerers to absorb it quickly.

comment Installing OpenGeo Suite in VPS windows?
As it stands I think your question is too broad because it appears to be asking at least three questions. I recommend that you edit it to focus on the single question that is the most important for you to have answered first as per the Tour.

comment Converting Feature coordinates to text (same as output from UNGENERATE command in ArcInfo Workstation)?
If you are trying to create the same output as Arc: UNGENERATE, then did you try the suggestion at gis.stackexchange.com/a/7344/115 ?

comment Is there a reasonable way to perform raster map algebra in open source web GIS?
@JohnBarça the extension suggested is to ArcGIS for Server and so is used in a web context.

comment Using Detect Feature Changes Tool in ArcGIS for Desktop?
Welcome to GIS SE! As it stands I think your question is too broad and risks being closed. Rather than saying effectively "I'm about to use tool X, and I am after anything you know about it before I do", I recommend reading the tool documentation several times, as you experiment with what it can do that helps you, and if you are then stuck to edit your question to ask a more focussed question about that.

comment Adding data from PostgreSQL to Query Layer of ArcGIS for Desktop warns that given coordinate references are incompatible?
Would you be able to also include the version of ArcGIS for Desktop that you are using and exact example values that you are feeding into the Query Layer when it works and when it does not, please?

comment How can i convert .tif file into headerless (flat) binary files?
@nilushika This looks like a new question that I recommend you research/ask separately.

comment What is the difference between `Area_2D`, `Area_3D`, and `Volume` in surface volume calculation?
You seem to be asking a near identical question for the third time. If there is an aspect that remains unanswered then I recommend that you edit this question to focus on just that aspect.

comment Error 000212 Cannot create XY event source from arcpy.MakeXYEventLayer_management?
This looks like it could be a duplicate of gis.stackexchange.com/questions/10225/… - if it turns out to be the same error message from a new cause I think we should consider merging the two Q&As.

comment Clip Management won't work outside of ArcMap/Catalog
When I see ERROR 999999 my first suspicion is always whether I have enough RAM available for what I am trying to do. If you are in a position to try the same code and data with much more RAM to see if it "just works" then that may save you a lot of futile debugging. If such a test is not easy then try using fewer, smaller datasets to as a test of your code logic.

comment Validating whether PDF file Uploaded as part of Geoprocessing Service of ArcGIS for Server?
Would you be able to include a code snippet from your code so far, that works up to the point where you are stuck, please? The answer seems easy - just use arcpy.Exists() to test whether the PDF has been uploaded if you know its name, if it does then append it, if not then pass. If you just want to test whether any PDF file has been uploaded then use arcpy.ListFiles() to look for *.pdf files in the folder you have them uploaded to.

comment What should be used for website building for displaying raster data?
Would you be able to review the answers to the question that I have made this a duplicate of, please? If you then think there is a unique requirement that you have which none of the options there cover, then if you edit your question to provide more details about what you have tried and where you are stuck then that is where our users may be able to assist.
