Create GIS database in PostgreSQL
1. Install PostgreSQL database (for example 9.6)
2. Install postgis module (for example 2.5.1)
3. Start pgAdmin 4
4. Create database
5. Enable GIS features in database with following command:
CREATE EXTENSION postgis;
6. Now shapefile can be loaded with PostGIS 2.0 shapefile tool
7. Set GEO input format (for example Rijksdriehoek)
SELECT UpdateGeometrySRID(‘wegvakken’,’geom’, 28992);
8. Create WGS84 geog column and fill it.
ALTER TABLE wegvakken ADD COLUMN geog geography(geometry);
UPDATE wegvakken SET geog = ST_Transform(geom, 4326);
CREATE INDEX wegvakken_geog_idx ON wegvakken USING GIST (geog);
9. Now pgAdmin4 can show GEO layer with OpenStreetMap layer as base.
10. Set center point of RijksDriehoek (Onze Lieve Vrouwetoren (‘Lange Jan’) in Amersfoort.)
SELECT * FROM wegvakken ORDER BY geom <-> ‘SRID=28992;POINT(155000 463000)’::geometry LIMIT 1;
11. select ST_X(geom), ST_Y(geom) from shapefile
Windows 10 upgrade takes hours
This afternoon my Quad Core 3GHZ Desktop finally received the Windows 10 creator patch. It took my desktop more than 4 hours to install it. Why is a Windows 10 patch always so slow? If i upgrade a Raspberry Pi Quad Core 1.2GHZ Linux kernel it’s only take 10 minutes. Strange that low end linux hardware upgrades are must faster than high end Windows hardware. I think that the Microsoft staff must go on training to learn how to patch Operating Systems fast and without reboots 🙂
Raspberry Pi Noobs cleanup
If you want to have a nice and clean Raspberry Pi Noobs installation. Execute te followings commands to remove unless tools:
sudo apt-get purge wolfram-engine (Reduce image size with 683MB)
sudo apt-get purge sonic-pi (Reduce image size with 151MB)
sudo apt-get purge scratch (Reduce image size with 93MB)
sudo apt-get purge scratch2 (Reduce image size with 147MB)
sudo apt-get purge scratch3 (Reduce image size with 147MB)
sudo apt-get autoclean
This initial Noobs image size will now be arround 4GB 🙂
Google Charts zoom in dataset example
I took me a while to understand how Google Charts can be extended with a zoom/drill in data set feature. You have to add then google.visualization.events.addListener method which fetch the selected datapoint of a graph. With some extra javascript code you can reload the chart with a more detailed dataset. See example below!
<script type="text/javascript" src="https://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("visualization", "1", {packages:["bar"]}); google.setOnLoadCallback(drawChart); function drawChart() { var options = { bars: "vertical", bar: {groupWidth: "90%"}, legend: { position: "none"}, vAxis: {format: "decimal"}, isStacked:true,colors: ["#0066cc", "#808080"],vAxis: { format:"decimal", viewWindow: { min: 0, max: ".round($max_forecast+100)." } }, series: { 3: { targetAxisIndex: 1 } } }; var data = google.visualization.arrayToDataTable([['','Low (kWh)','Normal (kWh)','Solar (kWh)','Forecast (kWh)'],['2006',0,0,0,0],['2007',0,0,0,0],['2008',0,0,0,0],['2009',0,0,0,0],['2010',0,0,0,0],['2011',0,0,0,0],['2012',0,0,0,0],['2013',0,0,0,0],['2014',0,0,0,0],['2015',0,0,0,0],['2016',20,20,11,278.75]]); var chart = new google.charts.Bar(document.getElementById("chart_div")); chart.draw(data, google.charts.Bar.convertOptions(options)); google.visualization.events.addListener(chart, "select", selectHandler); function selectHandler(e) { var year = data.getValue(chart.getSelection()[0].row, 0); link("pid=30&eid=88&date="+year+"-1-1"); } }
function link(value) { var form = document.forms['plaatenergy']; var newInput = document.createElement('input'); newInput.setAttribute('type','hidden'); newInput.setAttribute('name','token'); newInput.setAttribute('value',value); form.appendChild(newInput); form.submit(); }
