I've created a Google map that loads a KML file as an overlay. It is a map of trailheads for say hiking. What I'm trying to figure out now is how to create a search that will allow visitors to search within the KML's data and show the relevant trailhead/s as results on the Google Map. Is this possible? I have a google search that will let them search for an address, but this does NOT search within the KML file's data for a trailhead.
Ideally the visitor could input an address, say 12345 Main st., Chicago, IL, or something and it would display results that are within a specified vicinity, say ten miles, of that address (ie latitude, longitude).
I'm a little lost as to even where to begin.
thanks for your help!

I don't know how often your kml file updates, but i recommend storing all the kml data in a database as well to make this easier. Maybe every once in a while re-download the kml file and update the database.
Then its as simple as using the haversine formula and searching the database for nearby trails.
What you're describing sounds like a good job for Fusion Tables. Fusion Tables give you a nice way to store and edit the data (even collaboratively). In addition, there are geospatial columns/data fields you can add (aka, a "Location" column that can be address or lat/long coordinates). Put all the trail heads in your fusion table and you can map them. Let people enter an address or lat/long, and you can query the fusion table to show all trail heads within the user specified distance of that point. See the tutorials to get started.
You can use KML search tool to do this. It supports KML KMZ CSV and GPX. You can find the tool here

Total newbi here. I have played with studio for a few h but can not get over the next hurdle.
I would like to draw wine growing areas on the map.
Managed to draw areas. Tick.
I would like to give these areas a unique name.
Managed to create labels.
But I don't understand how the text is associated with the area.
I then want to search for this label, so that the map zooms in on that area.
Just like when I search for "Coburg, Victoria, Australia".
I have managed to publish my maps including the areas in my WordPress website.
So my access token and my style does the right thing.
Need some hints how to get the labelling and searching happening.
Thank you for any help.

and welcome to using Mapbox.

Have you tried creating a Symbol layer, and setting the Text field to the appropriate field in your data source?

This goes beyond using Studio, and into building web maps with mapbox-gl-js. One starting point would be to use the Finder Impact Tool.
This might involve processing the data twice -- once for your base map, and another time in a spreadsheet to make available to the Finder template. It's possible to just do once, but would involve some modifying the Finder template.

I am trying to create an index and skill that will allow me to
Index pdfs, multi and single page, and all other types of files,
Extract the Data and make it searchable,
Search for a term say "Cat" and have sections of text where the term appears to be returned, as well as the page number and document name / downloadable URL of the PDF/ image where it was found, a bounding box, would be nice but not necessary.
I am struggling, I have tried text extraction skill, OCR skill, but I am struggling in that the Search term returns the whole, extracted document (100 pages), as text in the file "content"
It's not making much sense to me, the JFK example is outdated.
I have spent 4 days on this, it cannot be that difficult, the documentation is not that helpful either.
I have tied to "build" and index and skillset using the portal tools, but getting a similar result.
any help would be appreciated.
You might want to try the hOCR custom skill, available on GitHub from the Power Skills repository if you prefer to use the hOCR format for bounding boxes, but [the OCR skill](https://learn.microsoft.com/en-us/azure/search/cognitive-search-skill-ocr#sample-text-and-layouttext-output's output) already offers bounding boxes for content. Note that the Power Skills repo also has updated versions of most of the skills used in the JFK sample, including the image store that can help you make pictures of the pages available in your app.
The key to making it work is in the skillset definition.
The JFK skillset has its OCR skill output layoutText.
There is also a custom image store skill that uploads /document/normalized_images/*/data and keeps the resulting URI as imageStoreUri.
Another custom skill transforms the OCR layout results into the HOCR format.
Then a ShaperSkill is aggregating that information under ocrImageMetadata.
In the case of JFK, that information then gets further aggregated under cryptonyms, because that's the main thing the JFK demo is focusing on, and the image metadata is also an output field mapping for /document/hocrDocument/metadata as metadata, which is also indexed. The important point is that all the relevant information is mapped to the indexed fields. As a consequence, the information therein becomes available from index query results.
Hey guys I have been looking around the net and I do not seem to find a viable answer. Here comes: I got a list of 1000ish addresses for which i want to get the coordinates. The dumb thing is that google maps gives me the coodrinates of each point but i gotta go copy/paste 1000 entries to get them, say in excel worksheet. I've seen sites that offer to get me the coords one by one which again is not viable for me. Is there any way to extract the coords of google maps, or any other site that can process large quantities at once?
Thank you
If you can write VB Script you can implement the Google API yourself, someone already wrote it for you: policeanalyst.com/using-the-google-geocoding-api-in-excel.
For bulk conversion just do a Google search, there are a couple of sites that claim to do it, this one works: findlatitudeandlongitude.com/batch-geocode
You can upload your file in text only csv format at
http://geocoder.ca/?batchupload=1&account=1
Then save the results back to csv, shapefile or even print on a map as pdf or png file.
I am working on a project to digitize approximately 1 million images for which metadata will be added to facilitate search.
Each image is, for example, a page in a dictionary. But not text. Just a static scanned image. OCR is not an option :(
My objective is to emulate the current search procedure which consists of looking up the alphabetical entries till the correct page is found. In absence of machine readable text, I am looking at tagging each page with Dictionary range tag. For Example (Apple-Canada). So if someone searches for "Banana", it should hit the (Apple-Canada) range Tag.
Is this supported in SharePoint out of the box? If not, is there an addon product which provides this functionality or am I looking at building a customized extension?
Any help will be appreciated :)
Installing the IFilter for TIF files is done with a couple of clicks and gives you free OCR along the way. Very good for scanned pages.
On your question though: No, SharePoint does not have any kind of "range" tags or fields. The only vaguely similar thing to what you are requesting is the Thesaurus of the search. There you could define acronyms and synonyms for words and it would actually search for something else. So you could enter Banana but it would actually search for Apple. Some examples here: How to: Customize the Thesaurus in SharePoint Search and Search Server.
Other than that I can only think of a custom implemented search provider giving you the flexibility you need.
I am trying to extract my KML file from Google's Fusion Tables into Google Earth. I follow what I think are the necessary steps via KML Network Link instructions. I must be missing something because no matter what I do the data will not show in Google Earth. I have the Fusion file shared as Unlisted, but am I supposed create a public URL as well in order for the points to show in google earth?
Sorry for the basic/beginner question. It's SO basic I can't find a question already addressing the issue.
Thanks in advance.
I can think of two things to check.
1) Your Fusion Table must be "exportable". Edit->Modify Table Info. Make sure the exportable checkbox is selected.
2) Did you rely on geo-coding addresses when creating your table? The lat/long values of geo-coded addresses in Fusion Tables will not be exported in the KML, and addresses might not display in Google Earth.
