hi @Ramos ,

please go to this repository and follow the installation instructions step by step, especially the package installation with renv, this will solve your problem:

Hello

What is the formula to obtain the mean displacement from the values ​​for each date?

I can’t understand how the final velocity value: mm / year is obtained

All the best

What is the formula to obtain the mean displacement from the values ​​for each date?

I can’t understand how the final velocity value: mm / year is obtained

We once discussed this somewhere in this forum, someone provided a good explanation, but I can’t find it anymore.

As far as I understand it, over the entire time period of your stack (lets say its 2 years for example), the velocity is calculated by looking at the absolute difference between the first and last point (lets say for one point that is 4mm) then you have a 2mm/yr velocity. However, there might be other ways to calculate that. e.g. calculating the velocity for the period 1st image to prime and a second velocity for prime to last image and then the mean of both results. But as far as I remember (I…

This is also one of the best post from Thho. Please check it once

That is what the subtract offset button in the StaMPS-Visualizer does, though not in StamPS in Matlab and neither do I know from the top of my head how to accomplish that, but should not be to hard. However, @asterios_papas, much of the plots is relative and I alwys need some time to wrap my head around it ;). If I do understand the PS plot of StamPS right, they are relative to the prime date, hence the first date does not start at 0. What the StamPS-Visualizer does is to simply offset all meas…

thank you @thho - this were the posts I had in mind.

hi @thho @ABraun , Can I install Stamps-Visualizer on version 7 of Windows?

[thho]

hi @despina98
Not sure but if the installation of R v3.6 is successful, there is a good chance that everything works out fine.

[despina98]

@thho the installation of R v3.6 is successful,but But when I call the Run App. The software opens but closes immediately and this warning appears:

Have you tried installing the colorRamps package in R (use the menu in Rgui or on the command line: install.packages("colorRamps"))?

[despina98]

@gnwiii @thho I tried both methods. How can I open the csv file of my case study area?

[despina98]

I want to install StaMPS_Visualizer on Windows 7 and open the CSV file in it. I have also installed R and RStudio software. Can anyone please send me StaMPS_Visualizer Package?

[thho]

Hi @despina98, from your screenshots, I can see that you use the first version of the visualizer which is outdated. Please go to this repo, clone or download the content and follow the installation instruction given also for Windows closely. I recommend installing all necessary packages with the renv method which is descried in the aforementioned installation guide:

GitHub - thho/StaMPS_Visualizer: Shiny application to visualize DInSAR...

Also, you will find instructions in the manual of the visualizer how to properly import your own data.

[despina98]

Dear @thho , Thanks for your good response, I followed all your instructions,Now how do I add my area to Visualizer? Why is it not seen here even though I copied it??

[thho]

hi @despina98, please provide:

• a screenshot of the …input/stusi/ folder where you have copied your .csv file
• a screenshot of the csv file open in excel or libre calc that we can check if the export from StaMPS was ok

Also be sure to restart the app after you have moved the .csv file to the stusi folder. At statup , the app checks this folder and adds new examples

[despina98]

hi @thho , I put the folder related to my .csv file below:

I fixed this problem but the file does not open؛

[thho]

Hi @despina98 , since nothing is shown in your map canvas, neither your points nor base map, the problem may be related to your windows 7 installation. Does the problem also appear when you select the demo data of the Maoxian case study?

[thho]

Ah one second! You do not have any internet connection right? That is necessary for the WMS tiles to be loaded. Please connect to the Internet and try again. It can also Be that your points appear beneath the control panel, just pan on the map canvas or disable the control panel by hitting the “toggle controls” in the upper right corner

[despina98]

hi @thho , No, this problem only appears when I open my case study file. There is no problem with the demo file.

[despina98]

I am now connected to the internet but I still have the problem with my file and it does not open
