I'm using the following imagery provider for streetView:
new Cesium.ArcGisMapServerImageryProvider({
url: 'http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer'
})
But it takes more time to load the layer. Whenever I'm loading the 3d model it is taking more time to load the entire layer. Is there any other streetview layer which is more efficient?

I wish to leverage a machine learning model in React-Native mobile app. The issue I have is I could not find a cross-platform method to bundle the machine learning model into the app and have the app load the model to be used.
For more context, I'm using onnxruntime-react-native to load a Machine Learning model in .onnx format. I'm trying to use the ONNX runtime to load the model when the app starts and use it for inference.
What I have tried is using the react-native-assets package and use readDirAssets method, but this is for Android only.
You can try to use react-native-fs. With react-native-fs you can get different paths in the filesystem and I think you need to get your MainBundlePath. However, you need to play with different path because the implementation of InferenceSessionFactory.create doesn't specify any formats.
RNFS.readDir(RNFS.MainBundlePath) // On Android, use "RNFS.DocumentDirectoryPath" (MainBundlePath is not defined)
.then((result) => {
console.log('GOT RESULT', result);
// stat the first file
return Promise.all([RNFS.stat(result[0].path), result[0].path]);
})
I am training a machine learning model in google collab and fixed the automatically disconnecting by using this code in the console inspector view of this question (Google Colab session timeout):
function ClickConnect(){
console.log("Working");
document.querySelector("#top-toolbar > colab-connect-button").shadowRoot.querySelector("#connect").click();
}
var clicker = setInterval(ClickConnect,60000);
However, after a given amount of time, all of my variables become undefined, which I require after the model has been trained. Is there any way to avoid this?
Source: Save / load model docs
I have trained multiple models on nodeJS side and saved them to using "file://"
So I have 1 JSON file, and 1 binary file with weights
But to load this model on browser side I can use only localStorage, indexedDB and HTTP requests.
What is the correct way to load them?
I cant just load from localStorage before I put a model there.
Maybe somehow I can convert my two files in something JSON-like and put it to localStorage?
IndexedDB is being cleaned after browser restart. Not sure if I can use it.
Http seems fine, but how do I load weights using?
await tf.loadModel('http://model-server.domain/download/model.json')
Its just a single file request.
Any ideas?
The weight files are loaded automatically by using the same path as the model file.
With your example the model file has url as following:
http://model-server.domain/download/model.json
The loader will load the weight files from following url:
http://model-server.domain/download/group1-shard1of1
As long as you store the weight files the same directory as the model.json file on the server, it should work.
I'm very new to ArcGIS and I'm currently exploring the js API. I haven't seen documentation for this but can i use a json datasource (returned from an ajax call) as the data items/points for my map? Can anyone point me to an example?
If you don't have any Map Service (ArcGIS, WMS, KML, etc) but just a list of geometries fetched from somewhere else you must use a GraphicsLayer. You can use the default GraphicsLayer of the map or add another GraphicsLayer.
for each geometry:
map.graphics.add(new Graphic(geometry, symbol));
I've been working with MapServer for about 2 hours now , but it seems alittle bit complicated to get started with.
So here's my question
Is there any way to get mapserver to show a simple map of whole world in which I can move the map to see different parts of the world ?
( from what I've learnt so far , it just shows you the Map you've passed the mapserv cgi , and the map is static and cannot be moved ! )
EDIT :
I'm still wondering if I can have a simple map for the whole world or a country or whatever ! Should I be Writing .Map Files for everything On my own ??
Okay , so after looking it up and struggling alittle , I found some JS libraries to do this, One of the was Open Layers. You just have to reference it at the beginning of your html page like :
<script src="http://openlayers.org/api/OpenLayers.js"></script>
and then you can have zoom and move options for your map by binding MapServer data as follows to the OpenLayers init function.
Var map, layer;
function init(){
map = new OpenLayers.Map( 'map' );
layer = new OpenLayers.Layer.MapServer( "NAME",
"http://localhost/cgi-bin/mapserv", {map: 'PATH_TO_.MAP'} );
map.addLayer(layer);
map.zoomToMaxExtent();
}
And lots of cool tutorials can be found in spatialhorizons.com.
Hope this helps someone :)
MapServer is just that, a MAP SERVER. It sounds like you are currently using a cgi script to display a hosted map. WMS providers like MapServer host data that can be viewed using a WMS client application. There are many such applications. You will need a more sophisticated client application to connect to the MapServer in order to perform more complicated map manipulations.
check out GoogleEarth
or NASA WorldWind
or I haven't used this yet but it looks like it might be the easiest, if least dependable.
First MapServer is the GIS server side technology. The zoom in/ pan is the client side behavior in my opinion.
When we look at the moment that user pan/zoom at one web application, what really happened is the front end application get the pan/zoom event and make calls to mapserver to get the new map to return to the client side.
So it is more likely your leaflet, Google map API, Openlayers, etc. are handling the detection of the client movement and parse it into new getmap request and send the request to mapserver to get the response.
What you saw from the MapServer using get request is static and it is suppose to be so. The dynamic part is happened in the client side to make dynamic calls from the front end application to make these static calls. That is interactive when client side dynamically sending out request and refresh the map from the response.
