Download Bulk Data from OpenTopoMap

databasedownloadopentopomap

Is it possible to download full regions of OpenTopoMap data ?

I saw that it is possible for Garmin devices (http://garmin.opentopomap.org), however, I am looking for jpg/png tiles and I could not find any easy way to convert Garmin format to tiles.

I am interested by OpenTopoMap as I guess this is the best data available for hiking in Europe.

You mean "OpenTopoMap tiles", not "data".

You can render your own with their open-source style from https://github.com/der-stefan/OpenTopoMap

That would be the nicest and most independent way.

You could mass-download their tiles with any suitable tool or script, but please ask them before for permission and rate-limits, see https://opentopomap.org/credits

PhoneGap and MBTiles.

WebSQL & IndexDB will not be enough. 'Windows Laptops' will not be the same code as mobile devices.

[GIS] Not able to bulk download MODIS images

Here is a quick workaround using the MODIS package:

# install.packages("MODIS")
library(MODIS)

MODISoptions(localArcPath = "/path/to/modis/files", 
             outDirPath = "/path/to/modis/files/processed")

runGdal("MOD13Q1", collection = "006", # see getCollection("MOD13Q1", forceCheck = TRUE)
        tileH = 25, tileV = 6, # MODIS tile id
        begin = "2000.02.18", end = "2000.03.31", # time period
        SDSstring = "110000000000") # SDS layers to extract (here: NDVI, EVI)

If you don't want to extract certain SDS layers, but deal with the raw .hdf files instead, simply use getHdf instead of runGdal and drop 'SDSstring'.
