Which format would suit your needs?

Totally fair—thank you for the honest answer. I get the “do-it-yourself” joy; I’m the same way with mapping.

Hi all,

I’m exploring a tiny service (website) for homesteaders/permaculture folks: I generate farm contours from public DEM and send you clean files you can use right away for planning terraces, ponds, access roads, or water harvesting.

What you’d get
Contours: 1 ft / 5 ft / 10 ft intervals (matched to data resolution in your area).
Formats: GeoJSON, DXF others
Coverage: Wherever public DEM is available (e.g., US 3DEP; other regions case-by-case).
Turnaround: typically 24–72 hours.
Pilot price: about $25 per 100 ha (fixed square/rectangle).

Why I’m asking here
Before I build more, I want to see if this is actually useful to you.

If you’re interested, a quick reply helps a lot:

1.What would you use the contours for?

2.Which interval helps most (1/5/10 ft)?

3.Your typical area size (acres/ha)?

4.Preferred format (GeoJSON/GeoTIFF/DXF/QGIS/others)?

5.Would ~$25 per 100 ha feel fair for you?

If you want to try the beta, DM me with a rough location (bounding box or pin), area size, and desired interval. I’ll confirm what DEM is available and send a sample before doing anything paid.

Thanks! If there’s real interest, I’ll formalize this and keep it lightweight and affordable.

Hi Everyone,

This post is an update for an older post. If you are looking to use LIDAR data to generate contour lines for your farm you should follow below link:

https://prd-tnm.s3.amazonaws.com/LidarExplorer/index.html#/

If you are interested in this topic or need help with the creation of the contours lines/ridge lines/watersheds etc from LIDAR data please contact me at adrrian.diaconu@gmail.com
Also please check the older post for more details

Hey you guys!

Just wanted to let you know that the LIDAR data is not anymore available on EarthExplorer.

LIDAR data can be found now at the below link:

https://viewer.nationalmap.gov/basic/

If any of you need help with contours ridge lines watersheds etc please write me at adrrian.diaconu(at)gmail.com

Thank you!!!
Adi

thank you all

Most probably your farm is at the intersection of multiple tiles of LIDAR data so that is why.

The easiest way would be if you could send me via email a KMZ/KML (Google earth file with the extents of your farm and also the products that you wish to have and I will get back to you.

Lookinf forward to hear from you!

Hi Travis,

It is hard to have a standard price. Because some have bigger farms and request only contours others have smaller farms and request more products (or I offer).

This is one thing another thing is what data is available.
Do your area of interest has LIDAR data?
What is the level of processing level of the LIDAR data?

Depending on these factors I can asses how much work would be needed from my side.

But to make it clear and simple the best would be if you could send me a KML file with the extents of your area of interest and what products are you looking to get. This way I will check analyze available data and make workload assessment and than I will get back to you on email with my proposal.

Example products:
- contours 2 ( foot interval) format KML or other as you wish
- digital elevation model
- aerial imagery
- drainage with streams and watersheds
- ridge lines
etc whatever else you will need and I did not thought about it.

So I wait for your email at adrrian.diaconu@gmail.com

Karen,

After you Create a new account on http://earthexplorer.usgs.gov/ and you sign in you should see an image like the one attached.

After this you start your search and you should download LAS or LAZ data which ever is available.
