How to create DEM in ArcMap

How to create a DEM from point data, how to make a 3D visualization and how to get 3D data from USGS

[@CAAU]

Excellent explanation, didatical and crystal clear. Thanks and regards from Brasil.

Sir may you please help me understand. In what format was the Grand_Canyon file. Was it a shape file?

[@aghiles4017]

yes you can see it at 0:48

Hi Jan Pacina, question: at the beginning of your video you start with point data from the Grand Canyon. Where did you obtain this data to create this layer?

[@packyGIS]

Hi. These data are from the SRTM downloaded at USGS explorer website. You get raster files from the site, but I have used the Raster to Point function (ArcGIS) to export the points.

[@unifiertwo]

where can you get the point data of an area you've used?

[@hiwabaiz8407]

thank you very much.

After exporting Basemap, have you georeferenced the JPEG file, or it is georeferenced? Because in my study area when I export it, it doesn't have a geotag, and also even when I assign a coordinate system to it in ArcCatalog, it doesn't accept it. I think we are not allowed to georeference the base-maps in that way. Maybe you have georeferenced the image using Georeferencing tool and control points.

[@MahmudulHasan-zc5qo]

The basemap is geo-referenced by web Mercator. so you can convert it to any suitable referencing system based on your demand using project raster. or you can project your vector data to web mercator

@@MahmudulHasan-zc5qo Hi can you give more details on the exported Basemap? I think it is lacking tutorial in this side because it is not working when basemaps imported to arcScence. FYI. Thanks

@@MahmudulHasan-zc5qo Assalamu Alaikum vai. Can you please give any suggestion regarding the problem? After loading the imagery or topography image on arcScene, it doesn't work the way it was supposed to be....How to solve this?

[@KaziAlmuqtadir]

Hi, can you tell me where you find that GA_texture in 11:48. I'm having problem merge basemap with DEM

[@sameh1393]

Yes me too want to know please!

[@prottoymobin3166]

@@sameh1393 Have you found any solution? I am facing the same problem :/ Please help if you can. Thanks.

[@sameh1393]

Prottoy Mobin unfortunately no , I hope that someone can help us 😕

[@KaziAlmuqtadir]

I fugired it out. First you have to download dem from usgs. Then download same image from google earth. Then geo reference it. Then you can merge them two together

Goodmorning sir! I want to know how to void filling in digital field measurement if you can help me with this please?

[@Refreshment01]

Where did you get the point data?

He said it alraedy.

Hi Jan, thanks for sharing this video, and it really helped me a lot. Maybe you can do me a favor to solve my problem at about 29:20 of the video: after inputting dem file with new raster into ArcScene, the background jpg disappeared in my case. I followed every step of the video and repeated for several times, but the same error was still there. Thank you in advance!

[@杨子-m2o]

i think the problem is that Elevation value is too big to the date dis disappear.

[@eyadjordan7623]

This happened to me too, do you find the solution ?

[@nanimoniz]

I bet you are right. This happened to me using Mt Rainer.

Resolution?...

[@onurdalgaboyu2]

Hi Jan, could you pls tell me how did you get elevation data (05:39)? I created points cloud by using fishnet method but I couldn't find elevation information?

[@packyGIS]

Hi there - the data are natively in GRID format - I use the "Raster to point" function in ArcGIS to convert the grid to points. The grid (elevation) values are then transformed automatically to the point feature attribute table (GRIDCODE)

[@hailutimerga4065]

would you explain me how to use map algebra in arc gis 10.1

[@alexferrari1226]

Hi Jan, how are you doing? can you help me with my college project? I am full of doubts. thank you in advance!

[@packyGIS]

Hi there ... what's on your mind?

[@eyadjordan7623]

sorry but im an architect student and im working on area i know, but what is mercator file and how to make one ? thank you

[@packyGIS]

You have to project your data - the USGS data are in WGS84 -> in ArcMap function Project

this video is useless, i came to here to see how to import DEM in to GIS, but you started the video by skipping this part. at the beginning of your video you start with point data from the Grand Canyon. Where did you obtain this data to create this layer?

Hello, can someone please help me in answering the following school questions have no idea. Question 1) Name four areas of application of a GIS and give a short example. Question2) In which two subcategories can spatial data be divided? For each two category, name two exemplary records. Question 3) What do you understand by data modeling? Question4) What steps are taken in the modeling of a specialized mathematics? Topic: Analysis a) Name three network analysisb and describe their number Topic: Databases a) Name two more data types of a geodatabase. b) Name four different numeric data types of a geodatabase and their (surrounding) value ranges. Topic: Visualization a) Name two card edge details. b) How are geometric and logical zooming different? Question4) For which applications do you use ArcCatalog and ArcMap? Give each two examples! b) Name two different formats for the digital storage of geodata! c) Name two geometric properties that you can calculate from the geometry type point. Question5) What specifications have to be made in the context of modeling? Please name at least 8 different definitions. Question 6) Which logical data models can be distinguished? Briefly describe the differences! Question 7) Explain the problem of generalization!
