Hi there,

I’m also interested in understanding the API usage costs for dataset downloading, and I noticed your question. Were you able to get any clarity or resolution on this? If you’ve found any useful information regarding the pricing or usage limits, I’d appreciate it if you could share.

Thank you so much for your help!

You can run the 1_sat.go up to the fmt.Printf("found %d required tiles\n", len(requiredTiles)) line and then multiply that by 64 (since the requests are for 512x512 tiles while requiredTiles is for 4096x4096 tiles). It is $0.60 per 1000 512x512 tiles (https://mapsplatform.google.com/pricing/). The price should fit within the free tier (first $200 usage should be free).

Hi @favyen2,
Thanks for your helpful explanation of the tile size costs!
For my research, I’m also looking for shapefiles on road infrastructure development (road upgrades or new constructions) over several years for a country or province. So , is it possible to obtain past satellite images, and how far back can I retrieve them? How long does it typically take to run the code you shared?
Thanks again for your help!

Unfortunately only one layer of aerial imagery is available from the API; there's no option for historical imagery and it doesn't report the timestamp of the images.

If you combine the most recent OpenStreetMap data with the latest aerial imagery then it should mostly match.

If you want to use a time series of aerial images to show changes in the road network over time, there are only a few free sources of this data:

• National Agriculture Imagery Program in the US provides 60 cm/pixel (some images are 1 m/pixel before 2018) imagery. A given location is generally captured at least once every three years. One way to access the data is via Google Earth Engine.

Actually that's the only one I'm familiar with, some EU countries capture aerial images and release it under open license too.
