USGS provide two kind of major Data sets, which are collection 01- Level 01 and Level-02 data. In Level-02 data All the other visual bands are process to surface reflectance but why panchromatic band isn't process? My question is how to process panchromatic band to surface reflectance? Can you suggest the method for me?
Hi Dear Researchers,
Providing some background information, I am an undergraduate student, completely new with QGIS, and I am about to use it in my graduation thesis. On the other hand, I am familiar with Qt6.
The thing is that I have seen people on the internet support QGIS with Qt5, but the corresponding resource for Qt6 doesnt seem to be available at the end of 2022.
I wonder:
- What is the benefit of supporting QGIS with Qt5? Is it worth to re-download a Qt5, since I have already got a Qt6 well-established on my PC, which really took me an effort to finish it?
- Is it doable to support QGIS with Qt6? Have anyone tried to do so recently? I cannot find much useful on the internet.
- What is the different between supporting QGIS with Qt/VS Studio, or using QGIS itself only?
- Any other suggestion for a fresh hand with QGIS? I believe it is a good tool for research but I am also eager to learn more about it more as a developer, and how to create real value and innovation with it.
I'd appreciate it if anyone could offer any guidance or suggestion. Really thankful!
Best regards and hope the best for your studies,
Jinghan
I have converted the raster to points in the GIS software and transferred table attributes to the Origin Pro program through an Excel file to draw a diagram. But there is a problem with it that I don't know which part it is from. Also, I encounter many errors in the Origin program, and only one graph is drawn from it. Can you please guide me regarding this problem by classifying the points? I have attached some Documents for a better understanding of the information.

Is there any good software that able to show the good results of spatiotemporal analysis of GIS outputs?
Hi,
Can I prove or model a reclamation in the past using GIS/RS? Can you provide me some discussion, readings, or techniques?
I want to ground-truth value (other than the DGPS survey) for the accuracy assessment of the digital elevation model for Indian region imagery. I want to compare the generated DEM elevation value with the ground truth value.
I bought climate data from IMD. Now I cannot open the .grd files. I want to use it in GIS. HELP! Aside from grads software, what else can I use to open the file?
I coordinate field operations for a farm with more than 5000 acres of blueberries and cranberries, divided into a number of fields ranging from 10 - 125 acres each. I was hoping to bring in a new system of data management for better grip on money and money out of each field.
By data, I mean chemical input, equipment usage, labour charges, and yields to have a better grip over every part of farm. This will help us plan variable applications and management.
As of now, I am looking for a GIS solution/software for data management, visualisation, analysis (to support third party statistical software), and decision-making.
I used the old ArcExplorer software as a lightweight viewer and mapmaker to publish migratory species distribution shapes on CD. Old Arcexplorer worked offline, but is now incompatible with modern windows versions (it does work in a Linux VM environment). I think it was the best compromise between flexible functionality and rapid learning curves, effective use could be teached in 2 hours! In contrast, the new javabased Arcexplorer is awkward and cannot digest my old arp projects. I think DIVAGIS is still in use, stable http://www.diva-gis.org/ and works offline, so I might use it for the next CD, if I do not get better suggestions.
As much details would be highly appreciated!
There is a few articles on the subject but in most cases they use some sort of actual data, and was just wondering if you could simulate flow velocity purely though GIS, and if so how?
If there are any links or videos to show how to do this that would be greatly appreciated.
Hello
Every one have article about drought with spi & gis softwave in 2017&2016?

During preparation of manuscript for publish in any journal, we have to mentioned sampling sites on map with the help of software by using Lat. and Long. I am looking for any GIS software which can help me to prepare sampling sites on map. are there any free GIS software and how can i make this map?
What programs are available and or which would be the best for this task?
I'm doing a master on moose populations estimations with a citizen science approch.
I want to simulate a hunter and a moose population (of known size) in the same landscape, "make them meet", and see how the abundance estimations are biaised depending of the proportion of "cheaters" (hunters who don't say the right number of moose seen).
I explored the SELES and RAMAS/GIS softwares, but I'm not sure they are appropriate tools to simulate two animal populations movements in a static landscape.
I have two test shape files (more than 50 points in each file) with slightly varied latitudes and longitudes, but same area (Bay of Bengal). Each file contains Latitude, Longitude and Data_Field as common headers.
I want to take average of the Data_field from these two files (may be nearest points of shape file1 and shape file 2) (an illustrate picture attached).
Eg.
Shape file 1 Lat1 Long1 Data1
Shape file 2 Lat1 Long1 Data1
Shape file 3 Lat1 Long1 Data1
Shape file 4 LatNIL LongNIL DataNIL
--------------------------
Shape file x Lat1 Lat1 Data1
--------------------------
I have read methods regarding Point Statistics and Cell Statistics in ArcGIS, but not succeed.
It doesn't matter about slight reduction of resolution, because I have high resolution data.
Two test shape files are attached here along with an illustration image of expected output.
Kindly help me to do this in ArcGIS.
Thanks a lot.
Are here any existing tools available that will estimate the snow line of an area once an image is uploaded?
I generated peaks of tree crowns as an individual pixels from DSM dataset, but there are some trees that have more than 1 peaks. I would like to integrate them based on the threshold value, for example I want to integrate 2 or 3 neighboring pixels that lay in 1 square meters and create one in the middle. I know Integrate tool can do this for vector dataset, but if I convert peaks to vector and re-convert to raster, there is a change in raster dataset which affects further analysis. My question is is there any tool in ArcGIS similar to Integrate which works for raster dataset. Or is there any tool to integrate neighboring pixels in any GIS software. Thanks in advance for any suggestions!
I am planning to build an agent-based ad-hoc network simulation to simulate animal tracking in the Savannah. For this I want to use AnyLogic's GIS functionality.
- Are there any limitations to the GIS functionality in the free PLE version?
- Are there any tutorial available on the GIS topic?
I have a aerial photo which is slightly oblique. I would like to use a free program capable to rectify images; this should be a preliminary step toward georeferencing the picture.
Many months ago, I found a small but effective program that used to do the trick, but I lost it and I cannot locate it anymore.
Can anyone suggest any free tool, preferably with a Graphical User Interface and stand-alone?
Thanks

ILWIS is an open source GIS software
From philosophical point of view, Classification point of view and GIS point of view. For example in a GIS software everything is treated as an attribute. In philosophy it is more difficult task. Please clarify
Hello
How and using which software can we depict raster base maps data as a graph or as a distribution curve?
For example two C factor maps (vegetation cover map) of two different dates.
There has been attached an example.
Thanks
I would like to learn how GIS software deal with TINs both via files and in the memory during execution. Any scientific or technical publication about GIS file formats would be helpfull. So far, the best references I have found are wikipedia (https://en.wikipedia.org/wiki/Esri_TIN) and this (http://vterrain.org/Implementation/Formats/ITF.html)
I am working on numerical modelling over a wide region between 20-50 Eastern longitudes and 30-50 Northern latitudes. I have lat-lon gridded bouguer anomaly and topographical data to use for my studies. Since I need to discretize the area into equal rectangles, I need to convert the data into metric system.
Is it possible to minimize the distortions when reprojecting? I converted the grid data to utm zone 34, It gave fake coordinates out of the zone. Both data fits on each other well on gis softwares. I am curious if I missed something here. After that I will resample it as 1km gridded surface.
Another question is, I am flattening the surface which is originally curved. This is another distortion for me because modelling program will read it as a pure flat surface. Also the rectangles I created will not be perfect rectangles in reality. How can I quantify the error?
thanks in advance.
For a study, I need to use MESMA in order to also account for within class attributes, however, I found conducting this method using ENVI rather complicated and tedious. I found VIPER tools by accident and now am curious if it is more convenient to use.
Can anyone recommend image-stitching and rectification software? I need to stitch ground-level images (Vis, IR and multispectral) of building facades into a "panorama" and then rectify them prior to export to ArcGIS.
Thanks
The shapefiles will be used in a doctoral research about palms that occurs in this region.
Thanks in advance.
I have data points within a number of polygons and I want to interpolate using the points within each polygon, ie the interpolation only using the points within each individual polygon to create an interpolation for that polygon rather than the whole surface. Any ideas other than interpolating just using the relevant points to interpolate and then cookie cutting with the relevant polygon? Thanks in advance :)
I have done some image processing which resulted me some 'n' number of bands with same resolution in tif format of same location. The number of rows and columns are slightly different in all the bands. Then I have stack all the layers and used 'extract values to point' tool in GIS but it didnt work. Then I have done it band wise it worked which took lot of time. Can any one suggest any alternative method in any other software or in GIS itself.
I am using 3 types of feature classes (Point,Line and Poly). Now I want to give some common field and name those features. How might I build a model using ArcMap10.1?
I am looking for your guidance. Thanks in advance.
Hello, I'm trying to find any toolset which can be used to map evapotranspiration in opensource GIS software like there is MODIS toolbox embedded with arcGIS.
And except MODIS what type of indian remote sensing satellite data can be used for evapotranspiration mapping.
Thank you
Hello, I am studying optimization land use, and looking for a RS or GIS software that have genetic algorithm. Can anyone help me?
Actually i want to make make landuse using Supervised classification using ground truth data.But i faced a problem,many pixel of other crops they classify in Bare land. Therefore is it possible i made threshold or model that assign Specific pixel values to definite class.
I have been reading more about ESRI ArcPad lately in ESRI publications. I haven't heard much about its use in a research context, however. I was curious if anyone has been using it and how. For a long time, I have wanted to have more field-based GIS data collection that updates more automatically to other GIS software. I thought this might be a good way to do that. Any thoughts?
It seems to me that ESRI ArcGIS has been dominant in GIS and spatial visualization and analysis applications for some time. However, some of my students have been talking about other GIS software. I know that QGIS is pretty popular as far as free and alternative GIS software goes. Has anyone out there used it for research or engineering that can share their experience? What do you like and dislike about it? How easy is it to learn? Is there a reason to use this free software as opposed to proprietary GIS software?

Hello!
I have run RF in Rattle using my AGB data (300 sample plots) as target and 15 variable (SAVI, NDVI, RDVI, NIR etc.). So I have two basic questions;
1. How I can know which tree, rule and node should I take for the spatial biomass estimation?
2. How I can apply selected rule on my spatial variables in ARCMAP (GIS software)?
How can we to compare levels of congruence between shape files and/or grid files?

How does one save raster as geotiff and later on convert it into grid format?
Dear All,
I have not been able to solve the hypsometric analysis issue using ArcGIS 10. Can anyone knidly give me the steps in using CalHypso, I have installed it in my ArcGIS 10 but it's not doing anything, it's not bringing up any suggested task to be performed.
Better still if there is suggestion of any method to be used in performing hypsometric analysis using ArcGIS 10, I will deeply appreciate if you could kindly give this to me.
Your kind immediate response will be deeply appreciated.
Alfred.
I usually digitize maps by creating a shapefile. Now I want to digitize by creating a coverage. I have tried several times but failed. Please help me.
I am working on a project using Arc map 10.2. I want to use 'Extent' and 'Cell size' from the option menu in Arc map 10.2. I added Spatial Analyst from the tools menu and enabled it to form extensions. Spatial Analyst was added to the toolbar, but the Spatial Analyst drop down box has disappeared. I cannot find out 'Option' menu.
Can anyone help me to improve this?
Should I remove 10.2 version and Install version 9?
The problem is a universal one.
