Thank you very much your videos have helped me in learning web GIS. eagerly waiting for test_query_panel9.html
Боже, благослови индусов❤ thank you for your lesson
Hello sir very useful video for me. i have tried this but quarry panel not working. kindly suggest me.
Nicely explain everything but I have a conceptual doubt regarding the WMS and WFS with respect to Raster and Vector , since the WFS exposes the features of a geometry in geoJSON so can we say that WFS is a Vector data service and WMS is always a Raster data service?
Hello Sir, thank you for this tutoriel, it's very helpful. Is it possible to have access to the file test_query_panel9 ?
Thank you for this video, is it posible to share test_query_panel9.html ?
Hello Sir, sir as I saw the session just before, are you gonna upload the recorded video.
Can we call geoserver apis from java ?
hello sir please explain me when given address of location is postgresql it shows longitude and latitude how to implemented query please help me sir...
Some kind of geocoding is needed for converting address to latitude and longitude....in my next video i will gonna explain how to render layer on the webpage directly from.postgis and also how to run spatial query in postgresql..
Can you explain architecture behind web gis ? What and how is openlayer and geoserver difference? How it is when using ArcGIS javascript?
I am trying to see ur all video trying to make difference?
Deployment of web map in website?
I make note of this - Openlayer as front end api and geoserver is serving geographic data
geoserver is kind of Middleware..which takes geographic data I.e shapefiles, raster files as input..and provides various services WMS, WFS etc.using which geographic data can be render on web (basically html) using web friendly formats geojson gml etc. This rendering is done using openlayers which is fronend api.Basically geoserver is serving geographic data, openlayers for rendering on web and .postgis for storing the data.
Gis data can also be directly rendered from postgis postgres database directly using openlayers (without using geoserver). As postgis can give various web compatible formats I.e gml,.gepjson etc. For this bit of backend programming is needed using jsp or php.
I had implemented similar feature query and spatial query using.postgis directly without gsoserver. But problem with that is this when you have very large data gml and geojson data takes large time to load and application becomes slow. Here WMS service of geoserver comes in handy. For visualization of raster and vector data WMS service is good.and for feature query and spatial.query WFS service of geoserver or directly postgis can be used. Hope this will clear your confusion.
ArcGIS javascript is just like openlayers but having more functionalities I.e basemaps 3d rendering etc
@@OpenGeoLab thanks for detailed reply. I got it now.
I would love to see videos regarding hosting these webapps/maps in websites.
What is procedures for that ... Do we need to ask/subscribe for geoserver seperately from website hosting companies like GoDaddy etc
Hello sir, I am unable to add point by using WFS-T insert, it shows the below error while inserting point
Error performing insert: java.lang.String cannot be cast to org.locationtech.jts.geom.Geometry
Can you please help me to resolve this issue ?, i am trying from 10 days.
Thankyou.
Maybe you have to add the GeoServer Namespace URI, with in the beginning, to your XML-request

If anyone want to publish a data-set of wrecks stored in a spatial database, They want to publish it as a web service usable in the browser by a web mapping library/framework, what technical factors would you consider before publishing.???
See if you are having spatial data stored in database....there are two ways for rendering that data on the web client side.
1.first through Middleware.. I.e geoserver...publish data in geoserver first...and then using WMS or WFS service data can be rendered in web...page using openlayers or leaflet..wms service create tiles in jpg or png format so..actual data will not be called..only tiles.is rendered on web page so rendering will be fast..further rendering speed can be increased by tilecaching WMTS service of geoserver you can check this video for tile caching...ruclips.net/video/7Xk4FoDZAIo/видео.html if you don't want to call actual feature on client just want to show on web WMS/WMTS service is good for you..
if you use..WFS..actual data is called and rendered on web..page..I.e geojson or gml format..so.it will slow ..if your data is large....but geoserver vector tile extension can be used for making it bit fast..if you want to call actual data for some geoprocessing or analysis wfs service will be good.
2. Directly render data from postgis spatial database to web client using openlayers or leaflet api...in this some backend programming is needed I.e jsp or php for parsing data from database in geojson/ gml format..you can check this video for second..it will be similar to wfs service of geoserver if you want to use option..check this video out.. ruclips.net/video/9N64Hy68Tww/видео.html

can we give labeling for WFS layer? please help me out

i need source code for test_query_panel9, pls
Hello sir thankyou fir guiding us about the GIS web development, I would like to request your to make a video on a project name test_query_panel9.html. I believe that you will consider my request. Eagerly Waiting for the tutorial
I will try to make video on that..
@@OpenGeoLab sir any update on that video, project named test_query_panel9.html.
God bless you
Thanks for sharing video.
What to do if number of features in layer are very high and want to add as WFS to allow editing?
How to add wfs layer with minZoom setting to layer is displayed at a particular scale only and limiting features with bounding box of the mapview?
you can use this url for loading features in your map view
localhost:8082/geoserver/wfs?request=GetFeature&version=1.0.0&typeName="+layer_name+"&outputFormat=json&&BBOX="+current_extent+",EPSG:4326"
current_extent can be calculated as follows using openlayers
var cur_extent = map.getView().calculateExtent(map.getSize());
At geoserver logged in page, on lower left side there is Demos option using which one can learn various various WMS, WFS, WCS queries.
Thanks for reply. I also want to restrict wfs layer to be displayed only after i zoom in to 17. How to configure it?
@@anjalhdave I think you can use minZoom and maxZoom option for vector layer..I never used it..here is the link for documentation
openlayers.org/en/latest/apidoc/module-ol_layer_Vector-VectorLayer.html
Thanks you Sir, it's a real tutorial.
Now I have question, it's possible to add a print function if I want to print a specific element.
Geoserver has extension for printing. following is the link for downloading extension and documentation of printing extension

Hello sir, Please provide us the link of file named test_query_panel.html
Will make complete video for that application...
@@OpenGeoLab it will be highly appreciated if you share or mail me that file at mail2gulsheet@gmail.com.
Thankyou in advance.
I wish someone can just simplify things create a webmap from scratch ...all in one video
I have already made a video for webgis development from scratch...ruclips.net/video/eAQcBGMPQTk/видео.html
I will make another detailed video including feature editing..
@@OpenGeoLab thank you very much will check it out
Do check it..this video describes webgis from scratch..from.downloading installing and configuration with feature query and spatial query implementation..

Good evening..>
hello sir, thank you very much for this video,
If possible, if you have a request to download the table from the application ...
Cordially.
Yes geoserver has excel csv extension..using that data called using WFS service can be downloaded as excel/csv
@@OpenGeoLab OK thanks a lot
I'm going to try...
@@OpenGeoLab Hi Mister
I tried but I can't download the table from the html application, please if you have an idea. thank you Sir
could you please make a video how it would be live ? if you have any live server ,please make a demo
Thank you
i will try
Me too, want to see it . If you can make such video.thanks
Nice work, pls can you sent Map Panel code
