-summary: "This article explains how to batch import rasters into a Postgres database. It also covers the use of PostGIS functions to query these rasters and create new ones. These techniques are particularly useful for applications such as QGIS."
-toc: true
-tags: ["QGIS", "PostGIS", "Database", "Raster"]
----
-
-## TLDR
-In this article, we walk through the process of obtaining and downloading rasters of global digital elevation data from the SRTM satellite.
-
-We split these rasters into tiles and import them into a local Postgres database using PostGIS.
-
-We then use tiles from this database to construct a query using PostGIS functions to generate a single DEM raster of Singapore and import this into QGIS.
-
-The final image looks like this:
-
-{{< figure src="/pics/blog/batch-import-postgis-rasters/singapore-final.webp" width="600">}}
-
-## Introduction
-It's possible to download the entire SRTM (Shuttle Radar Topography Mission) satellite imagery dataset and insert it into a Postgres database for personal use. This can be helpful for if you need global elevation data for your analysis and don't want to be limited by third-parties APIs.
-
-The SRTM is a near-global dataset of elevation data with a resolution of 1-arc-second (30m). More information is available from [USGS](https://www.usgs.gov/centers/eros/science/usgs-eros-archive-digital-elevation-shuttle-radar-topography-mission-srtm?qt-science_center_objects=0#qt-science_center_objects). 
-In this guide we will go through the process of downloading the data, inserting it into a Postgres database with PostGIS, then querying the final result to create a DEM for any country or region.
-
- This guide assumes you are using Linux (this may also apply to other Unix like systems such as MacOS) and have a Postgres database with the PostGIS extension installed. More information on how to do this can be found on the [PostGIS](https://postgis.net/documentation/getting_started/) website.
-
-## Download data
-
-We'll download the data from the [OpenTopography](https://portal.opentopography.org/raster?opentopoID=OTSRTM.082015.4326.1) AWS S3 bucket. You should create a free account with them before downloading. Also, remember to provide citations where necessary.
-
-To download the data, first we need to install the [AWS](https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html) CLI utility:
-
-{{< highlight shell >}}
-# install for linux
-curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
-unzip awscliv2.zip
-sudo ./aws/install
-
-# MacOS
-curl "https://awscli.amazonaws.com/AWSCLIV2.pkg" -o "AWSCLIV2.pkg"
-sudo installer -pkg AWSCLIV2.pkg -target /
-{{</ highlight >}}
-
-Next we can run the following command to download the rasters. This will take some time depending on your internet speed. The final size is about 127GB and took me about 1 hour to download on a 600MB connection.
-
-{{< highlight shell >}}
-aws s3 cp s3://raster/SRTM_GL1/ . --recursive --endpoint-url https://opentopography.s3.sdsc.edu --no-sign-request
-{{</ highlight >}}
-
-If you'd prefer to download specific rasters or rasters for a region instead, you can checkout this [website](https://dwtkns.com/srtm30m/).
-
-## Using raster2pgsql to import raster tiles into PostGIS
-Now we have the data downloaded on our system, we can import it into our database.
-If we look inside the SRTM_GL1_srtm directory, we can see all of the 14280 raster files: 
-
-{{< figure src="/pics/blog/batch-import-postgis-rasters/raster-tiffs.webp" width="600">}}
-
-Next we will use the `raster2pgsql` command to import these rasters into our database.
-
-{{< highlight shell >}}
-raster2pgsql -d -M -C -I -s 4326 -t 128x128 -F *.tif dem.srtm | psql --dbname=osm --username=postgres -h 127.0.0.1
-{{</ highlight >}}
-
-Here's a breakdown of the above command:
-- `-d` This drops an existing table if it already exists. It's useful to include this in case we need to run the command again.
-- `-M` This runs `VACUUM ANALYZE` on the table after the raster tiles have been inserted into the database. This optimizes the table by reclaiming storage space and then collecting table statistics.
-- `-C` This applies raster constraints to the table by using the `AddRasterConstraints` function in PostGIS. This adds several types of constraints to the table which ensures data integrity and enforces rules for consistency.
-- `-I` Creates a spatial index (GiST) on the table.
-- `-s` Assign SRID (Spatial Reference System Identifier) to the raster.
-- `-t` Tile size. This splits the raster into tiles of the specified size. Each tile is a row in the final table.
-- `-F` Creates a filename column. As the raster is split into many smaller tiles, this is useful to help us identify the original file the tile belonged to.
-- ` *.tif` Selects all of the .tif files in the directory.
-- `dem.srtm` Defines the schema and name of the table. Remember to create the `dem` schema in the database before running the command.
-
-The `raster2pgsql` command will output a sql query which we can then pipe into the `psql` command.
-
-For more information on the `raster2pgsql` command, please visit the PostGIS [website](https://postgis.net/docs/manual-2.1/using_raster_dataman.html).
-
-This process will take a couple of hours. It could take longer if running over a network, so it'd be best to run this command on the same machine as the Postgres instance.
-
-Once this process has completed, we can query the table to see how many tiles we have:
-
-{{< highlight sql >}}
-select count(*) from dem.srtm
-{{</ highlight >}}
-
-{{< highlight plain-text >}}
-  count  
----------
- 12009480
-{{</ highlight >}}
-
-So we have just over 12 million 128x128 tiles in the database.
-
-## Raster Clipping
-
-Now we have global SRTM data loaded in our local database, we can extract any of the tiles for further analysis and access this using any application. 
-
-Here I'll demonstrate using the following PostGIS commands: `st_clip`, `st_intersects` and `st_union` to create a digital elevation table for singapore and access this from from within QGIS.
-
-I already have countries vector data in my Postgres database that I extracted from OpenStreetMaps. You can download a pg_dump of this [here](/data/countries.sql) to insert into your database. Alternatively, I have a post [here](/blogs/import-osm-countries-data) that explains the process to do this manually.
-
-To create our table, we'll use the following SQL. I'll break down each section step-by-step.
-
-First we'll use the `st_intersects` command to select all of the raster tiles that intersect with the Singapore polygon. Note, we'll need to create a table, spatial index then apply constraints for this to work in QGIS.
-
-{{< highlight sql >}}
--- drop existing table and create a new table
-drop table if exists dem.singapore_srtm;
-create table dem.singapore_srtm as
-
--- cte to create polygon of singapore
-with country as (select geom as geom from dev.countries where country = 'Singapore')
-
--- select tiles that intersect with the Singapore polygon using a left join and st_intersects function
-select srtm.rast, srtm.rid
-from dem.srtm srtm
-join country ply on st_intersects(ply.geom, st_convexhull(srtm.rast));
-
--- create index and apply constraints
-create index on "dem"."singapore_srtm" using gist (st_convexhull("rast"));
-analyze "dem"."singapore_srtm" ;
-select addrasterconstraints( 'dem', 'singapore_srtm', 'rast', true, true, true, true, true, true, false, true, true, true, true, true) ;
-{{</ highlight >}}
-
-Now we can query the table:
-{{< highlight sql >}}
--- check number of tiles in the table
-select count(*) from dem.singapore_srtm
-{{</ highlight >}}
-
-{{< highlight plain-text >}}
- count 
--------
-   153
-{{</ highlight >}}
-
-Here we have 153 of our 128x128 tiles.
-
-We can visualise these tiles in QGIS:
-{{< figure src="/pics/blog/batch-import-postgis-rasters/singapore-intersects.webp" width="600">}}
-
-Note, you can use the `st_convexhull` command to generate an outline of the raster tiles as seen in the previous figure:
-
-{{< highlight sql >}}
-select row_number() over () as uid, st_convexhull(rast) as geom
-from dem.singapore_srtm
-{{</ highlight >}}
-
-It would be nice to remove the pixels outside of the Singapore polygon. For this we can use the `st_clip` function along with `st_intersect`:
-
-{{< highlight sql >}}
--- drop existing table and create a new table
-drop table if exists dem.singapore_srtm;
-create table dem.singapore_srtm as
-
--- cte to create polygon of singapore
-with country as (select geom as geom from dev.countries where country = 'Singapore'),
-
--- cte to clip tiles to the singapore polygon
-clipped_tiles as (
-select st_clip(srtm.rast, ply.geom, true) as rast, srtm.rid
-from dem.srtm srtm
-join country ply on st_intersects(ply.geom, st_convexhull(srtm.rast))
-)
-
-select rast as rast
-from clipped_tiles;
-
--- create index and apply constraints
-create index on "dem"."singapore_srtm" using gist (st_convexhull("rast"));
-analyze "dem"."singapore_srtm" ;
-select addrasterconstraints( 'dem', 'singapore_srtm', 'rast', true, true, true, true, true, true, false, true, true, true, true, true) ;
-vacuum analyze "dem"."singapore_srtm";
-{{</ highlight >}}
-
-Give us this:
-
-{{< figure src="/pics/blog/batch-import-postgis-rasters/weird-clipping.webp" width="600">}}
-
-Hmm, this doesn't look quite right! As you can see, the clipped tiles only seem to apply within the tile boundaries outside of the clip region. These areas have been set to `nodata` (which is expected). However, outside of that, QGIS is rendering those pixels as something else (it's rendering them as having a value of 0). 
-
-The reason for this is because we are not strictly importing a single raster into QGIS, rather we are still importing all of the indivitual tiles. Since GeoTIFFs are rasters that can only exist as a grid of pixels (i.e. a rectangle), QGIS must therefore render the entire raster extent, which leads to the unusual rendering issue above.
-
-We can solve this by using the `st_union` function in our query. This takes all of the individual raster tiles and unions them into a single raster. All of the `nodata` values for the extent of the clipped region will also be unioned, thus creating a single rectangular raster that we can import into QGIS.
-
-Our final query will look like this:
-
-{{< highlight sql >}}
--- drop existing table and create a new table
-drop table if exists dem.singapore_srtm;
-create table dem.singapore_srtm as
-
--- cte to create polygon of singapore
-with country as (select geom as geom from dev.countries where country = 'Singapore'),
-
--- cte to clip tiles to the singapore polygon
-clipped_tiles as (
-select st_clip(srtm.rast, ply.geom, true) as rast, srtm.rid
-from dem.srtm srtm
-join country ply on st_intersects(ply.geom, st_convexhull(srtm.rast))
-)
-
--- union tiles into a single raster
-select st_union(rast) as rast
-from clipped_tiles;
-
--- create index and apply constraints
-create index on "dem"."singapore_srtm" using gist (st_convexhull("rast"));
-analyze "dem"."singapore_srtm" ;
-select addrasterconstraints( 'dem', 'singapore_srtm', 'rast', true, true, true, true, true, true, false, true, true, true, true, true) ;
-vacuum analyze "dem"."singapore_srtm";
-{{</ highlight >}}
-
-{{< figure src="/pics/blog/batch-import-postgis-rasters/singapore-final.webp" width="600">}}

-The table below illustrates growth of businesses worldwide that accept bitcoin as payment for products or services. The accompanying chart displays the yearly cumulative number of bitcoin-accepting businesses for the countries selected in the table. The data is sourced from OpenStreetMaps and is updated approximately every 2 hours.
-
-You can select the growth period of interest from the drop-down, which updates the values in the table. The table shows the ***Previous*** value, which was the number of businesses *n* days ago specified in the drop-down. The ***Current*** value is the number of businesses as of the latest update. The table also shows the ***Absolute Difference***, and the ***Percent Difference*** between this period.
-
-The chart always reflects the countries selected in the table. There is a zoom feature on the chart to focus in on a period of interest.
