Steps to Interact with a Relational Database. If you want to learn python, read my guide that covers SEO with Python. INSTALLBASEPATH'HOME/local' cd mkdir build cd build -f Python-3.6.2.tgz wget tar -zxvf Python-3.6.2.tgz -f sqlite-autoconf-3240000. Here is an example of a script that will setup an encapsulated version (virtual environment) of Python3 in your user directory with an encapsulated version of sqlite3. If you don’t know SQL, make sure that you read my guide to help you learn SQL. However, as ngn999 said, if your python has been built from source manually, you'll have to add it.

The code 4326 is the spatial reference ID and depicts a simple latitute-longitude reference system. In this tutorial, we will learn how to use SQLite3 with Python. WHERE st_intersects(geom, GeomFromText(?, 4326))''', (polygon_wkt, polygon_wkt)) SELECT astext(st_intersection(geom, GeomFromText(?, 4326))) from my_line Line_wkt = 'LINESTRING()'.format(XA, YA, XB, YB)ĬurR.execute('''INSERT INTO my_line VALUES (?,GeomFromText(?, 4326))''', (1, line_wkt)) It’s not quite a simple as installing the newest version.

# '.so' (Linux) or '.dll' (Windows) to the extension nameĬonnR.execute('SELECT load_extension('mod_spatialite')')ĬonnR.execute('SELECT InitSpatialMetaData(1) ')ĬonnR.execute('SELECT load_extension('libspatialite')')ĬonnR.execute('SELECT InitSpatialMetaData() ')ĬurR.execute('''CREATE TABLE my_line(id INTEGER PRIMARY KEY)''')ĬurR.execute('SELECT AddGeometr圜olumn('my_line','geom', 4326, 'LINESTRING', 2)') Python doesn’t come prepackaged with Windows, but that doesn’t mean Windows users won’t find the flexible programming language useful.

Step 2 Download sqlite-shell-win32-.zip and sqlite-dll-win32-.zip zipped files. Step 1 Go to SQLite download page, and download precompiled binaries from Windows section.

# depending on your OS and sqlite/spatialite version you might need to add This chapter will take you through the process of setting up SQLite on Windows, Linux and Mac OS X. You could directly integrate your line into the database via a geometry column if you load spatialite as an extension of sqlite: import sqlite3 My second problem is that I don't know how to use the SpatiaLite functions in a python script. SELECT astext(st_intersection(polygon.geom, line.geom)) as XYĪs you can see, my first problem is that I don't know how to create a 'line' object in the table 'my_line'. I'm trying to write the code and I've come to this so far: #!/usr/bin/env pythonįichier=open('C:\MyPath\polygon.sqlite','r')ĬonnR =nnect('C:\MyPath\polygon.sqlite')ĬurR.execute('''INSERT INTO route VALUES (?,?,?,?,?,?)''', (1, XA, YA, XB, YB,'MULTILINESTRING')) It works just fine but now I'm trying to make it work in a python script with the XY coordinates of the line and the polygon.sqlite file as inputs. WHERE st_intersects(polygon.geom, line.geom) I've managed to make it work in QGIS by creating a shapefile for the line and then using DBmanager and the following SQL statement: SELECT astext(st_intersection(polygon.geom, line.geom)) as XY I'm trying to find the intersection coordinates between a line (knowing its start and end points) and a polygon (SQlite file).
