This proposal for a Geomatics and Remote Sensing site on Stack Exchange was brought to my attention via a comment on a question, but probably it could benefit from wider discussion, either on area 51 or here.
Perhaps changing the site's name (to reflect the encompassing of broader subjects) would be a radical change considering former discussions on this matter are not yet quite mature.
On the other hand, I believe we are mature enough to carry on some changings in our on topic help center page and emphasize the actual scope of questions on GIS SE.
Both the 'on topic help center page' and the tour page mentions the site is for cartographers, geographers, GIS professionals, programmers and database administrators.
I believe we could remove the highlight from what the person is, for what he/she is interested in, while encompassing all on topics subjects we have. For example:
Geographic Information Systems is a question and answer site for people interested in GIS, Remote Sensing, Photogrammetry, Geodesy, Spatial Database Administration, and Programming specific to the aforementioned.
Just to make a comparison, I find the description in the stats site, very clear about this aspect. They mention in their tour page:
'Cross Validated is a question and answer site for people interested in statistics, machine learning, data analysis, data mining, and data visualization.'
Note that although the site is strongly related to statistics (e.g.; the url of the site is 'stats'), other related subjects such as machine learning and data mining are welcome.
As a data point, here's a Google Trends search for 'GIS, geomatics and spatial'. It shows that GIS is the most popular search term.
Note that Geomatics is very small. It's not a well known term, so let's not confuse things by using something that has fallen out of favor in the industry and isn't popular in the broader community.
If we needed to change it, I'd suggest 'spatial.stackexchange'. But I don't think it needs to change.
I commented on that discussion, but it was suggested that I answer here too for visibility:
Just searching through meta.gis.se for some of the topics listed in that discussion reveals that our community has been discussing this concept for some time, and the general indication I get is that the topics are already 'on topic' for gis.se.
Like this one: Is my (remote sensing) question on topic?.
In short, this would be a change in name more than anything else.
I have explained here why we need a remote sensing community in the stackexchange and why most of remote sensing questions cannot be answered in either GIS or Earth Sciences. Because I wanted my proposal to cover geodesy, photogrammetry and surveying as well,I created a proposal named as Geomatics and Remote Sensing together with a discussion.
But what has been chosen as the name for the proposal or what has been said in the first post of the discussion are all just a suggestion. I've created them to know the opinion of experts like you and edit the proposal.
I didn't know the right way to draw attention to my discussion so I chose the wrong way of commenting below multiple questions so I beg the community to pardon me for my fault.
Unfortunately some members who saw the discussion just downvoted it without expressing their opinion.
I beg the members of this community who are GIS experts but are somehow familiar with remote sensing, geodesy, geomatics, etc consider my proposal in a favorable light. Come and express your opinions about every thing to make the best decision for the new proposal. I'm not an experienced person and I'm just a remote sensing student. We can edit the proposal and even change the name of it. So tell me what's the best. A better proposal will attract more attention and will be a complete resource for people like me together with the current community.
I give here some example questions that I think are not on topic for either GIS or Earth science
1- What is the most accurate algorithm to apply with use of hyperspectral data to predict soil organic matter>carbon prediction and soil moisture?
2-Why do Vertisols show high values in redness index image?
3-Do you know what type of surface indicates Bowen Ratio=0.34?
4-What are the main criteria to select frequency scales and orientations in 2-D gabor filtering for images?
5-Are you aware of the use of hyperspectral methods from aircraft to assess water quality?
6-Can we draw the spectral curve for a single pixel from a satellite image (for each band)?
7-How can we calculate thermal resistance from Landsat Image?
8-Does someone know the time scale of laser-induced electron impact dissociation of molecules, like nitrogen?
9-What aerosol types correspond to the Lidar ratio <10 sr and >80 sr?
10-How can I calibrate (or correct) my LiDAR intensity images and/or intensity values of point cloud ? What should be process steps for that?
11- How does rain influence wind speed measured with a doppler lidar?
12-Can you suggest a good soil model for simulating electromagnetic wave propagation (in the frequency of 100MHz to 3GHz) using FDTD tool?
13-Can someone tell me the interaction between C-band polarized SAR signal (and back-scattering) and temperate forests (deciduous forests)?
14-Does anyone know how I can get access to PolSARPro V5.0 (new version)?
15-In microwave data, which band and polarization is useful for mangrove forest analysis?
16-What is the proper methodology to delineate glacier extent using satellite remote sensing data sets?
17- Is there any postprocessing techniques for increasing sharpness of LISS 4 satellite images (5 m resolution) ?
18- How might I use the external DEMs in Sentinel-1 Toolbox?
19- Can we use c-band data for estimation of above ground biomass in woodlands?
20-How do I generate DEM using cartosat stereo pair?
21-Satellite sensor that provides both PAN and MS image?
22-Which pan sharpening method should I use for NDVI images?
23-How can I generate a precipitation from MODIS data?
And it was just a portion of remote sensing. If you tell me consider surveying, photogrammetry and geodesy and all subdivisions of these fields, I will definitely find more questions on the web that are off-topic for GIS and need a place to be answered.
Everything in remote sensing is not just change detection, classification, pattern recognition. Of course these kind of question can be answered in Cross Validated or image processing community.
Every thing is not the applications, they can be answered in Earth sciences
But if you tell me that Remote sensing, photogrammetry, geodesy communities are not needed in S.E, then I will definitely quit my support for the proposal. Because when I don't have the support of this community which is the closest to RS, there is no hope for a new site.
Because my point of view in this answer is not very similar to my previous answer, I decided to make a new answer
Regarding Andre Silva's answer and my comments below that, I thought maybe it would be better to concentrate on improving the current site rather than making a new site from scratch.
I had a brief look at the tags of the current site and totally I concluded that remote sensing questions are not always off-topic for this site but the site needs some improvements of course.
For example these are some tags related to photogrammetry, remote sensing and geodesy that I think GIS.SE lackS and I can find more if I study
active remote sensing, ALOS-PARSAR, antenna, propagation, AVHRR, Atmosphere, camera-calibration, deformation monitoring, electromagnetism, environment, environmental impact assessment, environmental management, environmental analysis, envisat, GLONASS, GMTSAR, hyperion, hyperspectral Image Analysis, hyperspectral remote sensing, interferometry, InSAR, laser, laser applications, laser remote sensing, laser scanning, lidar, lidar remote sensing, scattering, microwave remote sensing, optical sensors, passive remote sensing, phase unwrapping, photogrammetry software, physical geodesy, polarimetry, polarization,PolSAR, PolSAR decomposition, PolSAR pro, SAR Interferometry, satellite data, satellite geodesy, satellite image analysis, satellite image processing, light scattering, space geodesy, space photogrammetry, spectral analysis, synthetic aperture radar, target, TerraSAR, Terrestrial laser scanning, thermal remote sensing, vegetation, VLBI,water color, water quality
Because I'm not a geodesists or a photogrammetrist, so I don't speak about them but I suspect there are in the community who will focus on that fields.
But about remote sensing:
I think the current site has mostly covered sensors like Landsat, MODIS, etc that all act in the visible part of the spectrum. I didn't even find a tag related to SAR, InSAR, PolSAR. As I have discussed here SAR is becoming a major hot topic in the remote sensing community together with hyperspectral remote sensing. Again because I'm not much familiar with hyperspectral remote sensing, I can't help about that (maybe others in the community will help)
But my thesis is about SAR, so I know something about that especially about PolSAR. nowadays I ask my SAR-related questions in researchgate which in my opinion is not as good as SE.
I have a suggestion for this community:
In order to widen the existing site to cover microwave remote sensing, I will ask my SAR questions here and if they don't receive a proper answer in three days, I will make a comment to draw the attention of the moderators (@Aaron , @iant, @Mapperz , @PolyGeo , @underdark , @whuber ) to create a discussion in meta.GIS about whether the question is off-topic or not.Then if it's off-topic the community will think about new tags in the discussion and will decide what is the proper way to attract attention of SAR experts to the site
Is that a good way to widen the scope of the site?
