srtm4's Introduction

SRTM4 (Shuttle Radar Topography Mission)

Download and parsing of SRTM4 elevation data.

Carlo de Franchis, Enric Meinhardt, Gabriele Facciolo, CMLA 2018

Installation and dependencies

The main source code repository for this project is https://github.com/centreborelli/srtm4. It is written in Python. It is tested with Python 3.7, 3.8, 3.9 and 3.10.

srtm4 requires libtiff development files. They can be installed with apt-get install libtiff-dev (Ubuntu, Debian) or brew install libtiff (macOS).

Once libtiff is installed, srtm4 can be installed with pip:

pip install srtm4

Usage

In a Python interpreter:

>>> import srtm4
>>> longitude, latitude = 2, 48
>>> altitude = srtm4.srtm4(longitude, latitude)
>>> print(altitude)  # should be 174.613 (altitude in meters above the WGS84 ellipsoid)

In a shell:

GEOID_PATH=data ./bin/srtm4 2 48

For the crop function, if pyproj complains about the download of file, you can fix it manually with the command:

pyproj sync -v --file us_nga_egm96_15

srtm4's Issues

'tiffio.h' file not found on Mac

src/srtm4.c:9:10: fatal error: 'tiffio.h' file not found
#include <tiffio.h>
^~~~~~~~~~

I installed libtiff via homebrew: brew install libtiff, but I am getting this erroe when running pip install srtm4
Any suggestions?

pip install doesn't work on Ubuntu 18

Installing this package doesn't seem to work on Ubuntu 18, I think it has something to do with the libtiff package (I tried installing different versions of this package but it still did not work unfortunately).

Any idea if there is an easy fix for this?

 -ltiff -o bin/srtm4
    src/srtm4.c:9:10: fatal error: tiffio.h: No such file or directory
     #include <tiffio.h>
              ^~~~~~~~~~
    compilation terminated.
    Makefile:15: recipe for target 'bin/srtm4' failed

it returns wrong altitude

srtm4.srtm4(46.503,8.035)

gives for me:

srtm4.srtm4(46.503,8.035)
608.334

https://www.openstreetmap.org/?mlat=46.503&mlon=8.035#map=15/46.5030/8.0350&layers=C
is ca 2725 m above sea leavel ...

404 error

SRTM4 is currently returning a 404 error:

ConnectionError: Response code 404 received for url https://srtm.csi.cgiar.org/wp-content/uploads/files/srtm_5x5/TIFF/srtm_36_01.zip

When I try to go to https://srtm.csi.cgiar.org/wp-content/uploads/files/srtm_5x5/TIFF/srtm_36_01.zip I get:

Sorry, the page you are looking for could not be found.

Are these permanently offline or will they go back online soon?

Is there a windows version?

SSL Certificate issue

Trying to download a SRTM tile through this library gives the following error currently:

requests.exceptions.SSLError: HTTPSConnectionPool(host='srtm.csi.cgiar.org', port=443): Max retries exceeded with url: /wp-content/uploads/files/srtm_5x5/TIFF/srtm_21_05.zip (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1131)')))

When visiting https://srtm.csi.cgiar.org/ it looks like there is a problem with the SSL certificate that causes this. I tried setting verify=False here but that didn't solve the issue:

    r = session.get(from_url, stream=True, verify=False)

giving the following error:

ConnectionError: Response code 403 received for url https://srtm.csi.cgiar.org/wp-content/uploads/files/srtm_5x5/TIFF/srtm_37_03.zip

Which makes sense since the link to the SRTM tile seems to be broken: https://srtm.csi.cgiar.org/wp-content/uploads/files/srtm_5x5/TIFF/srtm_37_03.zip

Installation error on MacOS
