Firstly, I want to parse it to separated parts.

I could not make a code, using python, to do that. Would you help me please to parse the data and make the GeoJson format. The initial data format is like below. I generated the following code till now to separate the data parse them first, as follows, but it returns a line of data. I want the output to be line by line. Learn more.

In fact you don't need file. How should I do that then? Just press the yes symbol in the left of the answer, below the down bote button. Sign up or log in Sign up using Google.

The ones we find most useful are: ogrinfo - inspects a GIS datasource and spits out summary data or detailed information about the layers, kinds of geometries found in the file. If you want a comprehensive listing of options offered by ogr2ogr or ogrinforun the following at the FW Tools Shell. Note: for the above, you can leave out the host if its localhost and user and password if you have your authentication set to trust. In the below example, we don't want OGR to create a table called mytable.

We instead want to call the table something different like newtablename. To do so we use the nln option.

Sometimes OGR does not output the right projection, particularly with Units of Feet or data that has no projection info or the projection information can't be easily translated to your system.

In these cases you have to tell OGR what the output projection is. It has fewer idiosyncracies when converting data It has a lot fewer dependencies so can fit on your floppy. If you really want to use Ogr2Ogr for this kind of conversion, below is the standard way to do it. Sometimes you have more than one geometry field in a table, and ESRI shape can only support one geometry field per shape. Also you may only want a subset of data. In these cases, you will need to select the geometry field to use.

The most flexible way to do this is to use the -sql command which will take any sql statement. One way in which ogr2ogr excels above using the pgsql2shp tool is that ogr2ogr can export multiple tables at once.

This is pretty handy for sharing your postgis data with others who do not have a postgis database. The code below will export all your postgis tables out into a folder called mydatadump in ESRI shape shp format.

The code below will export all your postgis tables out into a folder called mydatadump in MapInfo. Now most of the time you probably only want to output a subset of your postgis tables rather than all your tables.

This code exports only the neighborhoods and parcels tables to a folder called mydatadump in ESRI shapefile format. So this section may be a bit obsolete for the upcoming versions. The tiger files contain a set of layers, so unlike the other outputs we have done, we will specify a folder to dump all the layers into. In the above, we are asking for just the CompleteChain layer and to output to a new file called sufcomp.

Note it will output shp and the corresponding shx, and prj files.

The below will create a folder masuf and output all the layers into that folder and give each a tab file extension. Note in the above we needed to put the -update -append option because OGR2OGR will try to create a folder if given a file with no extension, which translates to creating a new database.

Import 1 feature class and reproject and rename geometry column. MySQL 4 and 5 support spatial objects to a limited extent. The functionality is not as rich as PostGIS, but for basic mapping work and limited spatial analysis, and if you already have MySQL installed, it may suit your needs just fine. While OGR was designed primarily to transform data between different spatial datasources, it is a little known fact that it can be used as well for importing non-spatial datasources such as Dbase files and CSV files.

This is a tutorial provided by California Soil Resource Lab. To start using these tools.

Do you by chance know a way to batch-import numerous gxp-files with track points from a folder into the same spatialite table?

Great, a simple but great introduction to ogr2ogr commandline, I have to say that I was scared of this and used from qgis plugins, but now I saw that is good to have it into toolbox.

Post a Comment. May 23, Hence bye bye table names longer than 10 Characters very annoying!

Here are some examples that I have recently used in doing some batch conversions here and there between PostGIS, Spatialite and Shapefiles. Note your path to ogr2ogr is most likely not where I have it. Example 2. How to export all Spatialite tables into individual Shapefiles in an empty folder that exists. Example 3.

Using ogr2ogr to convert data between GeoJSON, PostGIS and Esri Shapefile

It is like salt in cooking you use it everyday. The task how to import a Shapefile into a PostGIS table that exists without overwriting the existing table and simply append some new geometries and match the attribute fields from the Shapefile to the PostGIS table fields. Read more. October 03, I'm using fontawesome 4.To use the data stored within them for web-based maps, they need to be converted.

Once you have the shell installed, all you need to do is open it, navigate to where your geodatabase or shapefile is located, and run:. The file size might be a bit big though depending on how much data you have. Tippecanoe works by splitting your data up into tiles at zoom levels, which can range from 0 to Each zoom level corresponds to a given level of precision from 32, feet to smaller than 1 ft.

The -zg flag will have Tippecanoe choose a max zoom level that should reflect the precision of the original dat. The —drop-densest-as-needed flag will have Tippecanoe drop the densest least visible features at each zoom level so tiles stay under Kb. Once the above code runs, I often like to check the output folder to see what zoom level Tippecanoe chose, then run it again setting the zoom level to be 1 higher.

For example, if Tippecanoe set the max zoom level to 10, I will run:. I then try mapping the data to see how it looks. Depending on how many features I want to drop, I will either use:.

Dropping feature attributes can help cut down the size of each feature, allowing more features to fit within a given tile. If you just want polygons and lines, without any feature attributes, you can run:. The above will result in the most performant vector tiles at the cost of losing all your feature attributes. Another good option for cutting down on file size can be to cluster points.

Tippecanoe allows you to do this a number of ways. As above, I usually run:. Depending on how the result turns out, I then change the zoom level or use —cluster-distance to get more accurate results. Now that we have an mbtiles file, we need to unpack into pbf protocol buffer binary format files it to be able to actually use it on the web. To do so, we can use mbutil.

Keep in mind that the pbf files are gzipped. So if you want to serve them locally, you would need to figure out a way to do it with the content-encoding gzip header set.

With your files converted, you need somewhere to store them. Once you have the shell installed, all you need to do is open it, navigate to where your geodatabase or shapefile is located, and run: ogr2ogr -f "GeoJSON" "outputFile. GetLayer 0 for feature in lyr: fc['features']. To find out what level of precision to use, I like to first run: tippecanoe -o out.

For example, if Tippecanoe set the max zoom level to 10, I will run: tippecanoe -o out. Depending on how many features I want to drop, I will either use: tippecanoe -o out. If you just want polygons and lines, without any feature attributes, you can run: tippecanoe -o out.Opened 6 years ago.

Closed 6 years ago. For some datasets we found that ogr2ogr was crashing with a segfault. This is the stacktrace of the core dump:. After a bit of investigation, we figured out that it was crashing because of a null pointer, and that situation happens when the input contains an empty array.

I want the user to be able to import a shapefile directly so I found out about GDAL ogr2ogr that has Java bindingsand can make this conversion with a single command such as:. Can someone provide me with an example of how to implement this? I'm using LibGDX if that's of any help. In the end, all i need is a way to convert shapefile to GeoJSON directly on my application so the user can add new maps himself, so any suggestion is welcome.

First you need to install the Java Bindings see here at the bottom. Than download the ogr2ogr. Than it gets quite easy. You just cann call ogr2ogr. Learn more. Asked 5 years, 4 months ago. Active 11 months ago.
