That link just brings you to the Code Sharing page. ArcGIS Code Sharing Esri must have redirected it.

Look into ArcPad for your GPS units, or maybe your GPS software can make Shapefiles. If needed the shapfile DBF's can later be brought into XLS.

I found Manning | ArcGIS Web Development to be very helpful as I played and modified a copy of GitHub - cmv/cmv-app: A community-supported open source mapping framework built with the Esri JavaScript API and the Doj… .It's not an easy read but does go into a lot of detail. However my current tasks are to create simple focused apps instead of complete do all solutions, and I was surprised to find I could do most of my mapping with Leaflet using the Esri plugin without touching Dojo.

The best avenue I found with Excel is to export it to a CSV file and bring that into ArcMap. Excel lets you use formulas, put text into X,Y fields, which problems plotting points. Another common problem is the Decimal Degrees being changed to an integer field and all the points plotting on top of each other. Joe is right, people treat it as a database, it's not. You just need to bring it in and convert it to one.

L.map is not a function is what the error screams. I'm not a Meteor user but you usually see this when the app doesn't see the library. In the Esri example they also call the Leaflet Library, your example just refers to the Esri lib not the Leaflet Lib. I believe you need both. Once your app can see the Library it show draw the map. <!-- Load Leaflet from CDN--> <link rel="stylesheet" href="https://unpkg.com/leaflet@1.0.0/dist/leaflet.css" /> <script src="https://unpkg.com/leaflet@1.0.0/dist/leaflet-src.js"></script> <!-- Load Esri Leaflet from CDN --> <script src="https://unpkg.com/esri-leaflet@2.0.4"></script>

Tough to see but there are 4 orange dots, may be easier to see if you turn basemap to streets.

I think your center coordinates are off. Try center: [76.641536,12.316173], This worked for me: require([ "esri/map", "esri/layers/FeatureLayer", "dojo/domReady!" ], function( Map, FeatureLayer ) { var map = new Map("map", { basemap: "hybrid", center: [76.641536,12.316173], zoom: 10 }); /**************************************************************** * Add feature layer - A FeatureLayer at minimum should point * to a URL to a feature service or point to a feature collection * object. ***************************************************************/ // Carbon storage of trees in Warren Wilson College. var featureLayer = new FeatureLayer("http://services1.arcgis.com/ECFqcT5baCSej64y/ArcGIS/rest/services/mysore1/FeatureServer/0"); map.addLayer(featureLayer); });

In the Esri example the css is https://js.arcgis.com/3.18/dgrid/css/dgrid.css, you can open this can copy/paste it to http://jsbeautifier.org/ so you can read the current css. Change what you want, save it as a new css file, then use the new css in your project.

I tend to bounce around from Leaflet to ArcGIS JS, and I saw in Leaflet we can use OSM Buildings. I have also looked at ArcGIS JS 4.0 with the 3D component. My playing with ArcScene has allowed me to create simple 3D building with flat roofs, and I know in OSM Buildings you can add in ridge lines and create 3D buildings with real roof shapes. So I started thinking is there a way to bring in OSM building and shapes into ArcGIS JS or ArcScene? Also is there a way to take the 3D shapes I create in ArcScene and export them into OSM Buildings? I like the idea that there is already a ton of data created by volunteers in OSM Buildings, using it in ArcGIS JS could save me time recreating it, not to mention if I create it in ArcScene, it could be used to help the OSM Building community. Has anyone come across resources, scripts, to convert this data back and forth?

I ran into this when I taught GIS at a college. For one class, students would use excel and their smartphones or GPS units and have trouble bringing data into ArcMap. First it was because they captured points as DMS and then you would explain why they needed Decimal Degrees, and show them how to convert DMS to DD. Next they would struggle because their new converted fields were really just formulas. Even if they had it as DD it usually came in as a string field, or they had 0,0 points if they used number fields. It was always a frustration lesson that finally had them using CSV as a simple fix.

Ah the advantages of using a spreadsheet for a database. You ruled out the obvious like spaces, characters, quotes, and nulls. Have you rules out the field names like longitude being shortened to long a reserved word? Field names with spaces also cause problems, if you ever plan to export as a shapefile the names have to be 10 characters or less without spaces or risk truncation. Check to make sure the cells also have values not formulas. Next step if you have checked everything ans it still doesn't work, try to export excel as a CSV and bring that in. If the X,Y fields still don't come in as numbers, you have a character in there somewhere, maybe a comma? Or if you have an older version of excel export as a dbf. Another option use Access, as an mdb files, import the excel table, ArcMap should now be able to read it. One thing you can count on is excel always being a problem, and people using excel as a database.

Have you looked at http://esri.github.io/esri-leaflet/api-reference/tasks/query.html ? My example was in Leaflet, In ArcGIS JS, you could basically do the same thing. Get the map extent on change and then query the feature layers. This code may help. require([ "esri/tasks/query", "esri/layers/FeatureLayer", ... ], function(Query, FeatureLayer, ... ) { var query = new Query(); var featureLayer = new FeatureLayer( ... ); query.geometry = feature.geometry; /////////////////////////////////////////Plug in current map extent featureLayer.selectFeatures(query,FeatureLayer.SELECTION_NEW); ... }); //////////////////////////////////////////////// require(["esri/map"], function(Map) { var map = new Map( ... ); map.on("extent-change", function(){ var geo = map.geographicExtent; /////////////Plug this into the query? console.log(geo.xmin, geo.ymin, geo.xmax, geo.ymax); }); ... });

I'm going the cursor route for now, as the spatial join works well but the table join takes A + B = C and I need a A + B = A+ like a standard join in the TOC. My constraint of not being able to delete/replace the data is it's in SDE and used for ArcServer and a standard REST service.

I have a featureclass of points and one of parcel polygons, my task was write some python code to put the parcel_ID back into the point. Without Arcpy, I just create a spatialJoin and then join the new fc back to the old one and field calc the data over and then blow away the temp spatialjoin fc. I thought this would be easy in python, except you cannot join to a featureclass you have to create a feature layer to join to. Since I'm allowed to modify the point feature class but not delete and replace, a join is out of question. I have roughly 11 thousand points to update. Since I have to do this with the county poly, municipal poly, zipcode pole, etc, the manual method is not an option, they need a tool. I imaging I could create a cusror to step though each point and then do an intersect to get a field value and update a record but is their a better way?
