Extract DEM, DTM from Stereo Pair Images Using Imagine Photogrammetry (LPS)

[@hippolytedandonougbo9949]

Thanks for the video.
I have a question please.
How can I divide an ltf file into many portions so that many people can work on its edition?

[@narimanezaabar4549]

Thank you? Please I have pléiades tri- stéréo images , i should use the same tutoriel ? For Dem extraction ?

[@AlejandroAyala1]

Hi! Thanks a lot!
I've a question.
How can I delete selected points in the Editing Model fase?

[@GeoSpatialTutorials]

Yes you can, You can search DEM editing google

[@zainabazhar681]

Hi, can you suggest a geometric model for aster 3n and 3b bands?

[@venkatbangaram5335]

Dear sir,
Please tell me how to place manual grid points in lps.20 60 grid

[@adekambiadefemi7025]

Hi, How can i getthe right rpc for world view imagery from digital globe? the resolution is 50cm

[@Lono42]

Exactly what I was looking for. Thanks!

[@GeoSpatialTutorials]

Welcome.

[@nareshm7603]

Sir.
Did u show also AT
Here
So can we create At?

[@pratibhas7112]

while deriving the DEM, how do i set the vertical datum to Geoid EGM96 ??

[@Kooksrifles]

Nice video! Do you have an idea why I get a constant Z offset between my result and a correct reference dtm? the scenes match nicely but my result is almost constantly 15m higher ...for another test area I have the same issue but there my scene is about 10m lower...

[@GeoSpatialTutorials]

I am not sure. May be you can contact the image provider. However if the values are varying constantly, may be you can change the values accordingly

[@koushikrafsan5820]

sir, how can i download stereo pair images for free..please give me some suggestion or website link..

[@worldonthisday4424]

HI SIR
I GOT RMSC 0.4523... , IS THAT OK FOR CARTOSAT IMAGE ?

[@fitrarayhangeodet5900]

Good morning, sir. How to convert data DEM to DTM ? Use software global mapper or another

[@tusharlohar2617]

sir, can i generate DTM from DEM image using LPS.

[@amiriftikhar2284]

i have extracted dem from stereo pair images of world view 2 using 6 GCPS..but dem elevation is about 12 m incorrect from ground survey elevations..kindly tell me the solution.. thanks

[@GeoSpatialTutorials]

You may have to do DEM editing. But I cant teach it online as it requires personal presence. You can try to contact some professional directly.

[@gayanendrasengar4436]

Sir , could u provide DEM/DTM extraction using eATE tool with stereo pair images in eradas 2016 lps suite

[@GeoSpatialTutorials]

I do not have it for 2016 because I do not have this version of ERDAS

[@VanyaShivakumar]

Dear Sir
Could you please let me, If there are any stereo pair images for testing this. Please suggest

[@GeoSpatialTutorials]

I do not think that stereo pairs and support file will available for free.

[@VanyaShivakumar]

I am successful creating DTM using your Video. Thank you for your help.

[@GeoSpatialTutorials]

Thank you for the comment

[@aurangzebrehmani]

i am using erdas 9 i facing problems regarding new version please explain this tutorial on erdas 9

[@chinnikc8102]

How to terrain edit tools working please share me terrain edit toolls

[@charushiladesai]

Thanks for sharing your knowledge with us.
There is one request. Please kindly upload tutorials on use of Python Language in Arc, Q and Grass GIS.

[@vishnue2868]

I would like to know the steps for creating 3D city model (3D buildings) from worldvew/ very high resolution stereopair data.
Please provide suggestions sir

[@GeoSpatialTutorials]

I do not have video on that. If I create I will surely upload

[@vishnue2868]

If possible, Kindly share the methodolgy or write the steps. so that it will be so helpful. Thanks for your reply
[e-mail]

[@GeoSpatialTutorials]

I dont think its possible to explain over text. You may try some online material or contact someone working on that in your area. They will be able to give practical exposure

[@vishnue2868]

Sir,
I am trying to add frames in Imagine Photogrammetry.. I am stuck with an error popup always.
Unsupported Compression Type:-
If am clicking on OK to ALL:-
It will show a pop up with "Unsupported Compression Type Layer Unable to Open".
Why this is happening?
If am procceding with this error: On automatic Tie Point Selection-Am able to get 44% accuracy only"

[@dmtv_5559]

Please how can I create DEM from SPOT IMAGERY in ArcGIS10.3

[@GeoSpatialTutorials]

I don't think is possible. You will have to use some photogrammetric software

[@gayanendrasengar4436]

sir could u provide video about feature collection tool in stereo analysis.

[@gopik5410]

How to generate DSM sir using ERDAS or DSM extraction from DTM

[@GeoSpatialTutorials]

I have not done that. May be you can check the manual

[@gopik5410]

Procedure said by you is to generate DTM which is a bare eart model?

[@GeoSpatialTutorials]

Ya, uts DTM. If I =remember correctly ERDAS has an option to convert it into DSM

[@sandhyamary9731]

Hello sir.. I got negative z values.. can you please suggest me a way to eliminate this anomaly?

[@GeoSpatialTutorials]

Negative values are possible if its coastal area. However if you feel its anomaly then you have to edit the DEM, but I cant teach you that online. Either you will have to try with photogrammetry manual or find someone who can teach you in person

[@sandhyamary9731]

While doing triangulation, the result shows negative z values for all the automatic tie points.. pls send me your mail id.. i'll send you the screenshot of the triangulation report

[@sandhyamary9731]

Thanks for your support sir

[@GeoSpatialTutorials]

[e-mail]. But I suggest you to do it once again, hopefully that works

[@mapscale5415]

Tnx.plz send to download demo link

[@allgames5947]

thanks, please i want the logiciel erdas imagine 2014

[@srinidhiparashar165]

Sir please show HOW to extract Lineaments from the DEM...

[@GeoSpatialTutorials]

I advise you to use a satellite image and use edge enhancement technique

[@subbunaidu1529]

HI HOW TO CRATE LTF FILE

[@mesfindelelegn1165]

thank you so much

[@PankajSharma-my8vp]
