When the application starts, it is kinda slow to load the map at run time.
Is there a way to save the leaflet map in local or improve the loading speed in browser?
What is a leaflet map for you ? Remember Leaflet itself loads the content from a tile provider.
If you don't want to request the tile map over the internet, you may download one locally and somehow link leaflet and your own installation.
OpenStreetMap allow users to download their own tile provider.

If you want to store your leaflet objects (like markers, paths, etc.) the localStorage Javascript's variable can help you.

I need to display ArcGIS ESRI map hosted in intranet environment.
I was following this example and it works fine when system is connected to internet.
As our Map Server is hosted in intranet environment so I cannot use above example.
I have further investigated ESRI leaflet and found out that its making calls to online arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer for loading map tiles. I replaced this URL with our Map server URL
https://{our domain}/intsrv/rest/services/Cache/StreetsNightBlue/MapServer but still tiles are not loaded.
I have added all required CSS and JS files offline in my project already.
mapObject = L.map('mapDiv').setView([defaultLat, defaultLong], defaultZoom);
L.esri.basemapLayer('Gray').addTo(mapObject);
L.esri.Cluster.featureLayer({
url: 'https://{our domain}/intsrv/rest/services/Cache/StreetsNightBlue/MapServer/0'
}).addTo(mapObject);
When I run program, in console it giving tile not found error.
Update: Tiles appearing now but far away from marker cluster
Kindly help to fix this issue.
Does leaflet.js send through any announcements or call-outs for new providers added to their repository like through email or on their landing page?
Leaflet dev here.
No, we don't.
Leaflet is provider-agnostic. As long as you provide OSM-style XYZ tiles, or TMS tiles, or a WMS service, Leaflet will be able to use it.
It's up to you to reach users. It's also up to you to send a pull request to be included in the list of Leaflet plugins, if you choose to make a Leaflet plugin for your basemaps.
I am just wondering how I can go about publishing a feature layer in arcmap, and save that as a service to arcGIS for server, so I can call the service in my code in order to generate the feature layer for a web map?
So far I can only find resources in regards to publishing a feature layer to ArcGIS online. I am wanting to publish the feature layer from arcmap to arcGIS for server and call from javascript API to generate a web map.
There are two main ways I use to do this. I first log into my server with the ArcGIS Server installation. Open up ArcMap on that system. It is basically the same thing as a regular ArcMap but has a couple more tools you will be using. Mainly, you will be using the Map Service Publishing toolbar. It contains tools that allow you to analyze, preview, and publish your map.
Set up your map document to show the layer in the manner you want it to appear when you're showing it in a web application. You can set symbology, scale dependencies, labeling, etc...
Once that is set, you need to publish it as a service. I work off 9.3.1 but 10.x should be pretty similar. I believe in the 10.x installations, you must analyze your map before it allows you to publish. It is a good idea to analyze it anyway because it gives you suggestions to get the app running faster.
You have two options when publishing a map to the ArcGIS Server. You can publish the map document as a service or save a map service definition file. I typically do the map service definition files because it is supposed to render faster (according to ESRI).
This ESRI link gives better, more precise information too: http://resources.arcgis.com/en/help/main/10.1/index.html#//0154000003vt000000
Best thing to do when you're first starting out playing with this is to go to videos.arcgis.com and search through the developers presentations from ESRI's Developer Conferences. They are typically hour long segments that have presenters going through and describing how to do all sorts of things with ESRI software.
I am assuming you're using ESRI's JavaScript API to consume the map service. When you publish a service, you get the option to share it as a WMS service too. That would be more useful if you were using open source tools like OpenLayers to consume the map service.
This is a bit of an introduction into doing this. The major problems you may have is getting administrative privileges on your server and making sure the user accounts are set up properly. My biggest hiccups came from not having permission to administer the server.
Let's say I have a site where local users can upload their favorite hikes to share. But some users don't have the ability to get gpx or kml data.
Are there any open source options for the users to plot their own hikes, like in a google maps window?
If not, what would be the best way to go about doing this, if any?
Thanks for your time.
You can use the Drawing Tools in the Google Maps Javascript API v3 to plot the hike, then convert that data to KML or gpx.
proof of concept built from a previous version of blitz-gmap-editor, there were some changes made to it since I took that snapshot.
I have a strange issue regarding caching of the Maps js API for which I couldn't find any solution.
My situation is as follows:
We want to display a simple website including a map based on Maps API v3.
The website shall be displayed on an embedded device which uses a modified WebKit engine.
Therefor displaying and using Google Maps works great.
But here comes the problem:
Our embedded device has only few storage space (maybe a few 100 KBs).
The Maps API caches every map tile (which usually makes sense!!!), so after the user is moving around the map for some time, we get an error that the cache is full.
Is there any possibility to tell the Maps API not to cache the tiles, to only cache a specific number of tiles, or even to remove the cached tiles programatically by ourselves?
I couldn't find any approach or solution regarding this issue, so it would be really great if somebody has an idea.
Thank you in advance
