Otto Linnartz




I have spent the last couple of days hunting down the Linnartz Home. Otto Linnartz was a manager/executive/owner lumberman for the PETRICH SAUR Lumber Co. He lived on South Street for a while and relocated to Avant when Highland Park was newly developed. Finding the location of this house was a little more complicated than the other searches I have done. I found the advertisement first while I was looking up a totally different house in Inverness (the neighborhood just south of Steves). As newspapers in 1920's San Antonio had no concept of privacy, I thought it would be easy to pop in Mrs. Otto Linnartz and find the bridge club or singing troupe or temperance society meeting with the address. It turns out that Mrs. Linnartz only showed up at other people's parties ... she never threw her own. So I had to revert to another way to track down Otto and family. I used the Bexar County Clerk's website and searched the historical records for Otto Linnartz as a grantee of a deed of trust in 1924. I found the pdf only after I asked a good friend with Internet Explorer to perform the search. It turns out that the Bexar County Clerk's office used a contractor named Landata and the bid was completely oblivious to the world of browsers, the website only works for Internet Explorer. That piece of crap application crashed three different browsers on my Mac ... Firefox, Safari and Opera all crapped out when I went to get the pdf.

The pdf of the deed of trust listed the neighborhood / block and tract numbers for the property. Here is where I had to get crafty. With the numbers off of the deed I want into the bcad (Bexar County Appraisal) search engine and looked up a property I knew was in the neighborhood. That lookup gave me the neighborhood number. What I wanted was the geographic ID ... so using the neighborhood number I used the map search interface of the BCAD and turned on the GEO-ID layer under the parcels option. I started scanning through the neighborhood looking for a block and tract number that matched the ones on the deed and sure enough ... I found the street and bounding block. I then switched over to google maps street view and walked the street until I found the house that matched the picture of the Highland Park advertisement. I also pumped in the geo-id into the Bexar County Appraisal District search engine and did a sanity check for the street number and name and valuation of the house.

Screen Overlays In Google Maps

I have been playing around with screen overlays as a method of dealing with legends and branding. I found that My Maps does not support the kml elements you need for screen overlays or folders, but it is possibe to have an server host the kml files with the tag and the tag. Because I am cheap, I use google sites to hold all my files. I offload my kml and images on the files of a bogus endpoint I create in mySites.

you can offload your mayMap kml file by adding &output=kml to the http call on the page that shows your map.

I used this sample file I found on the google map forum. And used it as a template for the asian_overlay kml file.



I edited and reset the namespace and the tags from my My Maps kml .. and added folders too cuz I thought it made the map more comprehensible. I used a standard text editor to add the elements.

old namespace:
<xmlns="http://earth.google.com/kml/2.0">

new namespace:
<kml xmlns="http://www.opengis.net/kml/2.2">

and I threw in an atom tag for good measure:

<atom:author>
<atom:name>myName</atom:name>
<atom:author>
< atom:link href="http://www.mysite.org" >

In the screen overlay entry I pointed to a png file I wanted to use.

<Folder>
<name>ScreenOverlays</name>
<open>0</open>
<ScreenOverlay>
<name>screenoverlay_absolute_bottomright</name>
<visibility>0</visibility>
<Icon>
<href>http://sites.google.com/site/mapsofoldsanantonio/files/nowcast_2010_logo.png</href>
</Icon>
<overlayXY x="0" y="-1" xunits="fraction" yunits="fraction"/>
<screenXY x="0" y="0" xunits="fraction" yunits="fraction"/>
<rotationXY x="0" y="0" xunits="fraction" yunits="fraction"/>
<size x="0" y="0" xunits="fraction" yunits="fraction"/>
</ScreenOverlay>
</Folder>


Once the files were uploaded to mysite. I created a url based on the template:

http://maps.google.com/maps?f=q&hl=en&q=http%3A%2F%2Fsites.google.com%2Fsite%2Fmapsofoldsanantonio%2F%2Ffiles%2Fasian_overlay.kml&ie=UTF8&ll=29.4916,-98.5011&sspn=29.5301,29.4027,-98.3586,-98.6563&z=10&om=1

where the sspan parameters are in the following order:
newGLatLng(map.getBounds().getNorthEast().lat() − map.getBounds().getSouthWest().lat(),map.getBounds().getNorthEast().lng() − map.getBounds().getSouthWest().lng()).toUrlValue()

the %2F is actually an escape code for a / .. so this would be the html path to your new and shiny kml file. From here you can grab a link or the embed code and you are off to the races.

Some elements may need tweaking: the ll and spn elements may need tweaking on your embed to center on the elements you wish to capture on the map.

Historical Dignowity Hill


View Dignowity Hill San Antonio in a larger map

All I have is a couple of maps today. I have a much more nuanced appreciation of the central city after all of the reading and mapping and research.

Here is a map of Cruz Ortiz's favorite haunts on the East Side. I actually met one of the co-founders of Sew-Delux and have not had a chance to check out the place. Its on the list ... the list is crazy long and includes a fishing trip to Mission County Park.

I love driving to the west side on Steves Avenue ... from Steves its an easy little jaunt to the river and the Blue Star. I also love using Nolan to hook up to McCullough and San Pedro (okay okay really I mean the Luby's on Main ... Nina loves the jello and I love the ladies in the Sunday hats) ... no trains on Nolan and a fast entry to downtown w/o getting on the freeway.
