I am trying to create a heatmap in QGIS, and most guides suggests using the heatmap plugin. The only problem is that it is not showing up in my QGIS installation. Do you have any suggestions?
SOLVED:
Apparantly in the new version of QGIS, you just go to the properties of your points, and then you can do a heatmap there under styles.

I recently started working on Flutter and started to build an app but now I was hoping to integrate google maps. I started to look more into google_maps_flutter and started to build the map but one thing I'm currently being unable to integrate is to draw the shortest route between a provided source and a destination.
I have looked into google_maps_flutter plugin but unable to find the implementation of the aforementioned functionality.
Any help will be appreciated.
If you've checked the tutorial about Flutter - Using Google Maps and drawing Routes, this is a structural guide that you are looking for building an app to draw route between two places.
Aside from the package google_maps_flutter as mentioned in the tutorial, you might also like to consider using the package google_map_polyline_new since google_map_polyline was discontinued 2 years ago.
Is there a decision, how to use Grafana's Worldmap with zabbix 3.0.3?
I do not understand how to send geo information from servers to zabbix and from zabbix to grafana. I want to do something like this (on the first screenshot) - servers with errors on the map.
Thanks.
https://grafana.net/plugins/grafana-worldmap-panel says:
World Map panel for Grafana. Displays time series data or geohash data
from Elasticsearch overlaid on a world map.
World Map plugin is not for Zabbix. It's only for data from Elasticsearch.
Zabbix provides maps - https://www.zabbix.com/documentation/3.0/manual/config/visualisation/maps/map - use some nice map background and place your hosts into maps. Use different icons for different host problems states and result will be probably ok-awesome.
https://github.com/SpawW/zabbix-extras is project for Zabbix 2.2/2.4, which provides also Zabbix integration with Google Maps. It's not ported for Zabbix 3.0, but you can try.
I have very little experience in GIS. I am working on a project were I need to put around 120 coordinate points on a web map using openlayers 3. There are also attributes associated with these points. I added the points from a csv into arcGis. I turned them into a shapefile. I also have a web map with a satellite image of the area. It works and opens in a browser.Now what do I do? Can someone point me in the right direction. Thank you
The shapefile can be converted into a GeoJSON (e.g. with an online service or QGIS. The GeoJSON can then directly be consumed by OpenLayers:
map.addLayer(new ol.layer.Vector({
source: new ol.source.Vector({
format: new ol.format.GeoJSON(),
url: 'path/to/your.geojson'
});
});
You need to upload your shapefile on a server in order to publish it on your map via web protocols like Web Map Service (WMS) or Web Features Service (WFS).
Take a look at the OpenGeo Suite, it should get you started. You can install GeoServer locally to develop and test your application, and then migrate it all on your web server.
Another option would be to use QGIS GeoExplorer to directly have a working interface with differents options.
I have a web application where I want to show the car patrolling on the Geo map. Is it possible to integrate QGIS map for web application.
You can export the QGIS map in kml and then load the kml maps in google maps I think this is the simplest way.
For QGIS you can export your layer in KML with right click on the layer, then save as format Keyhole markup language.
For import KML in google maps you can see this google developer sample
https://developers.google.com/maps/documentation/javascript/examples/layer-kml
There are many ways to achieve this. The simplest is to use the plugin qgis2leaf. There are many howtos and videos about it, one of them is Leaflet Web Maps with qgis
EDIT: In answer to a comment, to install qgis2leaf, as here:
Go to menu Plugins ‣ Manage and Install Plugin
Search for "qgis2leaf" (if it is not on list, try to enable Show also experimental plugins on the Settings tab)
Select "qgis2leaf" and then... INSTALL!
I am developing windows store app using ESRI map. I have installed ArcGIS Runtime SDK (Beta2).
Using that SDK how can I load KML data to the map. The new Beta SDK missing of KMLLayer class.
Thanks in advance.
The current beta does not include KML support but we plan to add this in a future release.
The ArcGIS Runtime SDK for .NET product is still in beta, therefore please submit your questions and feedback in the beta forum: https://betacommunity.esri.com.
The .NET Runtime mentions KMLs but does not give any samples on how to load them.
https://developers.arcgis.com/net/store/guide/maps-and-layers.htm
Other types of specialized layers provide the ability to add a wide range of data and services to a map, for example WMS services and KML.
