Google indexes ‘Related Maps’ aka GeoRSS feeds

Saturday, June 27th, 2009

Just stumbled on this today, and not seen it noted anywhere yet, but (recently?) Google has exposed its index of ‘Related Maps’ on Google Maps.

If you open the ‘Show Search Options’ option, there is an entry ‘Related Maps’ - this mainly seems to be GeoRSS feeds its found out in the wild, but does include maps from ‘My Maps’, but strangely not KML files (which are mostly indexed in User-Created Content I guess)

Oh and if you where wondering, yes did find this when checking something out on geograph. (Note the link at the top to view Related Maps)

Still waiting for the day when we get good access to Googles GeoIndex, the AJAX Search API gives very limited (32 results max, and no urls! oh and doesnt include all the options included in the ‘options’ dropdown on Google Maps either), feels so this data could/should be exposed more?

MGRS coordinate entry

Friday, December 12th, 2008

Prompted by one of those infernal* posts on a Google Maps group, have finally been inspired to cobble together a MGRS -> Lat/Long conversion. It seems trvial, the UTM->MGRS conversion is quite simple, but there are a few gotchas!, so after much puzzleing over some C code from GeoTrans (and Trial&Error for good measure!), I think** have something working.

Anyway try it out here: 

Coordinate Flyto for Google Earth/Maps

also added today is a tickbox to open the result direct in Google Maps (rather than Google Earth). 

I’ll tidy it up and post the code, which is based on the PHPcoord conversion class, incase others have a use. I’ll also add it to the API - and possibly even back port it into Perl for use on the on site coordinate covertor. 

Finally possibly of interest is the realisation that the MGRS Google Earth Gridlines layer, will actully load directly in Google Maps, so:

MGRS Gridlines in Google Maps

the lines should update a few seconds after dragging/zooming. Ideally will suppress the big blue pins (which are show as numbers in GE) , but not tonight…

 

 

* in the nicest possible sence!

** I tested it by converting utm->mgrs->utm globally on a worldwide 1 degree grid - all check out with absolute precision.

Between a rock and a hard place…

This is going to be a long and rambley piece about licences and the updated updated Terms of Service of the Google Maps API - if either of those don’t interest you turn away now :)

Not that long ago Google updated the Terms of Service on Google Maps API - I guess mainly in responce to issues brought up on the Mail group, and elsewhere. As a result of that edit there where many concerns raised (and more)- and a further edit was made. (note, only linked to some of the blogs etc - follow links to read more) This was over a week ago, but due to non online commitments haven’t really had a time to follow this up. You can read my early reaction here, which has been edited in to Mikes post.


Below is the main section that is still causing concern, quoted in its entirety:

11. Licenses from You to Google.

11.1 Content License. Google claims no ownership over Your Content, and You retain copyright and any other rights you already hold in Your Content. By submitting, posting or displaying Your Content in the Service, you give Google a perpetual, irrevocable, worldwide, royalty-free, and non-exclusive license to reproduce, adapt, modify, translate, publicly perform, publicly display and distribute Your Content through the Service and as search results through Google Services. This license is solely for the purpose of enabling Google to operate the Service, to promote the Service (including through public presentations), and to index and serve such content as search results through Google Services. If you are unable or unwilling to provide such a license to Your Content, please see the FAQ for information on configuring your Maps API Implementation to opt out.

11.2 Brand Features License. You grant to Google a nontransferable, nonexclusive license during the Term to use Your Brand Features to advertise that you are using the Service.

11.3 Authority to Grant Licenses. You confirm and warrant to Google that you have all the rights, power and authority necessary to grant the above licenses.

To be honest still unsure how I feel about this section, and finding it very hard to vocalise (well to put to pixels) the concerns. I certain its not compatible with a number of situations where the Maps would otherwise be ideal, but that I guess is real life - just need to move on an find something that is more suitable. But its still gauling to have invested so much in Google Maps API to have it all disappear in puff of legal smoke, I guess its now going to be“Once Burnt, Twice Shy” as they say.

Content on Google somehere, somehow?

Saturday, August 16th, 2008

I don’t know if anyone is interested in this stuff, but have been for a long time being trying to make sence of the various ‘geo’ properties operated by Google and quite a bit on how to get indexed and exposure for your content.

Update: There has been some misconception about what this diagram represents - it is only intended to cover getting content in KML/KMZ files on your website listed and indexed in Google Properties. It’s sort of murky in that content you submit to other websites are sort of included to show they end up in various indexes. It does not cover business listings at all which for the most part is sepetate totally.

Edit your MyMap container

Saturday, August 9th, 2008

Small update to the My Maps support in GoKML, announced a few days ago; you can now edit the links contained in the file. Just goto your secret admin page, generated for your link.

People viewing your file in Google Maps will see the update soon, Google Maps caches it for a while.

People viewing in Google Earth however will not, as they downloaded a static file, which brings onto another point, if want them to auto update as well, could create a network link to your Container, using the standard GoKML form, (enter the url your container and choose appriate refresh period).

My Maps Container

Wednesday, August 6th, 2008

When using the Google’s My Maps feature you can display multiple maps at once simply by ticking the boxes, however the ‘Link to this Map’ will only ever include 1 map, so you can’t easily send a group of maps to someone.

… So a new script - this time under the gokml.net banner - for creating a ‘container’ KML that simply opens a bunch of maps at once - this KML is openabe in Google Earth, but also you can share the link so others can see your batch of My Maps at once in Google Maps.

Create a KML container for a group of My Maps


As a total aside I notice My Maps, now sport a (Geo)RSS feed :)

Google Earth 4.3: Magnetic Compass

Friday, August 1st, 2008

A while ago released a Compass Overlay, which (hopefully) makes reading directions of the navigation control easier. Well this new version does the same, but its (mostly) correct for the Magnetic Direction!

Magnetic Compass correct link this time!!

Note: its positioned to fit the navigation control of Google Earth 4.3, not the separate compass, which has only recently begun working for me… Updates a few seconds after stopping moving.

Now have a way to determine the magnetic variation at a location have some other ideas for using this in Google Earth, eg magnetic bearing along a line, but this is a starting point. For example in the uk the variation is often too small to be really seen on the tiny control.

Thanks to heywhatsthat.com for the pointer to a webservice that gives the variation.

Update: Rather embarrassingly just noticed the link above was wrong! It was to a static compass. The link above has been updated, and it should now rotate! Sorry for confusion… (always wondered why this didnt get much traffic!)

Google Earth: Chart Plotter

Sunday, July 27th, 2008

Did someone mention a chart plotter? If so have a look-see:

Google Earth: Map Plotter

Its hot off the presses so don’t know what options it will need yet, just used three example zooms levels - other options would include the mobile map style. (You can change it by altering the link in Properties)

Also its standard Google Maps, as that is all the API offers. Ideally would be proper flight plan data, but would need a Static Map API to work.

Note: The map is centered on the camera position (so is ideal for the Flight Simulator) - and while it can be used in other modes it wont make much sense. If interest could make one that shows the center of the view itself.

Disclaimer: this is entering the gray area of what is possible with the Static Maps API, so might get pulled, etc.

More flight sim tools

Google Earth: Flight Simulator GPS Arrow

Saturday, July 26th, 2008

Behold a new network link from nearby.org.uk:

Google Earth GPS

Once you have chosen a destination point, a small arrow will be shown in the bottom right of your Google Earth window, which points towards your destination! Ideal for use in the flight simulator, where you can play follow the arrow.

Note it only updates every 5 seconds, and comes with all sorts of disclaimers such as don’t use in life or death situations.

Letting your KML loose

Thursday, June 26th, 2008

I think I have mentioned this before, but have a page that helps share your KML file via various Google services.

Following a post on the Maps help group, realised could update it with some other ways to use the KML (even non Google!)

So view the latest page at

Publishing your KML for Google Earth, Google Maps and Beyond

suggestions for other links welcome in the comments!
