Help with config.xml

JoshuaCoates

I have been working with Flexviewer for a few months now and have been slowly making progress creating a web app. I am having some minor issues that are rather annoying to try and conquer. I am going to try and keep this simple and straightforward in hopes that a few people can help guide me in the right direction. I have read the help pages and getting started resources, however, these do not exactly cover small steps that can be rather mundane but also confusing, or so I believe.

I have created 6 map services. I have the following: a basemap of the county, 2007 floodplain, 2007 cross sections, 2010 floodplain, 2010 cross sections, and a 2008 ortho of the county. All of these 6 services have been cached to optimize the browser speed for viewing.

I am trying to create a very simple application when users can zoom, pan, and perform simple address searches for the county. I have all the layers in each service setup with min/max in order to display at certain levels. I want to have this application have the basemap of the county to always be visible. All the other layers I want to have the ability to be turned on or off at the users choice. I would like to have all of the layers, including the basemap, to be visible in the layer list widget I implemented in case users want to turn layers on or off.

My troubles are a few: 1)The basemap layer is listed as my basemap layer and an operational layer, however it does not appear in the layer list. 2)I also have implemented the dynamic legend and for the basemap layers....they are all repeated twice in the dynamic layer once I am zoomed in to where all the layers in basemap are turned on?! 3) When I click on the arrow for a layer in the layer list, it drops down with the sublayers but there is no box to turn those sublayers on/off. (this may be due to the fact that all the services are cached and therefore cannot be turned on/off separately in the layer.

I am adding my config.xml for reference, if anyone can see something I may have set up wrong, please let me know....

I tried calling. If you can, feel free to call me back when you get a chance. 770-833-0013

Josh,

ESRI_StreetMap_World_2D is a combination both raster and vector layers, as you say, but once you use a raster layer, then you want to use JPG. Generally, if you want to create a service that you can put above another service and be able to see the service below where there is no data in the service above, you would want transparancy, and that requires PNG. JPG is for services that will be at the bottom of your stack, and will serve as your "base." Personnally, I wanted my users to have the choice of whether they wanted my streets service by itself, or to be put ontop of other base layers like hillshade or aerials, so I made the service PNG8 with the white areas transparent. Other folks like the look and simplicity of the ESRI service. Is the data that you are trying to mix with this layer only vector? Feel free to call me if you want, it might go quicker that way, especially since we are getting off topic for this forum I think. 707-543-3112

JoshuaCoates

So is the world street map considered raster or vector? It seems to have both types of data in the layer??? What would be best to cache this as if I just need the two scales I mentioned? Thanks for your help btw!

MikeHargreaves

A couple of things first. Why are you choosing PNG24? If you are using something that has hill shading, then you probably won't be needing to have transparancy. Aerials and other raster based layers are best to do in JPG with a compression of 60 and a tile size of 256. Your goal here is to minimize the size of your downloads to the user, and PNG24 produces large file size, and takes longer to cache. If you are doing something where you need transparency, then I would try to do it in PNG8 since that will also keep file size down. The only time you would want to use PNG24 is when you are using anti-aliasing, which causes the number of colors to exceed what PNG8 can handle. Personally, I just use PNG8 for vector services, and JPG for rasters. Next, I'm curious why you have scales of 128,000 and 200,000, since normally you want to double the scale each time, though if 200,000 is good enough to cover your area, then I guess that could make sense...

So, to your question of caching only a portion. You can do this in a couple of ways. In ArcMap, the easiest way is to first set the visible extent to what you want it to be, and then right-click on Layers in the TOC and select properties. In the Data Frame tab click Other and then Specify Extent. Once there, click on Current Visible Extent. You could also explicitly set your extent if you know it. Also, while you're here, make sure the Coordinate System is correct. The other way to do only cache a portion is to do it when you are actually doing the caching. At the bottom of the Manage Map Server Cache Tiles dialog, you have the ability to "Update specific areas using a feature class" where you can supply a rectangular feature class that covers your area. I would choose the first way myself...

JoshuaCoates

Ok here we go, this is sounding better. I may have just not performed the task correctly. I need to have it projected to match my basemap, in State Plane. I can do this....now, how do I set up the full extent and where do I do this? When I treid caching, I only tried to cache at 1:200,000 and at 1:128,000. Which are the first two levels of display on my basemap that I want the ESRI service visible for. No levels cached at all so that leads me to think I may have been trying to cache the entire world as you mentioned.

I am trying to cached in the exploded format, png24. And our internet and intranet connections are great.

MikeHargreaves

Josh,

Did you try doing it with just the online service to see if you could cache that? I tried it, putting it into a different coordinate system and it worked fine. A couple of questions - did you set up a full extent in your mxd? If not, you are probably attempting to cache the whole world... Were you able to cache any scales? What format (jpg, png8, etc) were you caching in? How good is your internet connection?

JoshuaCoates

Well this is a complete bummer. I do not think I could handle the coding. I just cant figure out why I can not cache my basemap with the ESRI layer added?? It makes no sense?!

rscheitlin

Josh,

Are you ready to jump into some real coding? That's what this will take You will have to modify the MapManager.mxml to turn on and off the esri basemap using an event listener for extent changed. As far as the units ESRI's basemaps (the newer ones that the viewer uses) are in webmercator WKID:102100. There has been several discussions of this in the old forum.

JoshuaCoates

Ok maybe this will work.....can someone chime in if they know best way to do this.....

Can I put the ESRI map serivice as my basemap and set it up to show at my initial extent of my county? And then have it set up to where it turns off at another extent? This way I could use my basemap as an operational layer and everything would work fine?! I just cannot figure out what units the <map initialextent> uses?!

Josh C.

MikeHargreaves

Robert - thanks for the tips.

Josh,

Not sure what is causing the cache to fail, though your idea of only caching individual scales should help you identify what is causing the problem. If you bring a different service into the mxd, and that service is in a different projection, it could be that the system is timing out, since it takes awhile for the tiles to be reprojected. If the scales are different, then ArcMap will take the nearest scale to what your map is in, and then zoom in or out depending. This can cause it to look blurred somewhat, which is why the earlier comment about wanting the scales to be similar. I have another map that you might want to look at: http://pmaps.ci.santa-rosa.ca.us/geocortex/essentials/web/viewer.aspx?site=County It is not a flexviewer app, but it is one I did of our county, and it contains surrounding county boundary and road info that is available in your ESRI data disks. It might not look as snazzy as the online service, but it would be another way to go.

JoshuaCoates

Mike, yes the cross sections are operational layers, I have them under the operational layers. I have all my streets, addresses, parcels, building footprints,etc in a map document called basemap. I also just added in an ESRI basemap service (streets) into that mxd and tried to re-cache it. It gave several errors about failing to create tiles at extent xyz.xyz. I was told that I could use any tiling scheme as long as there were close to the ESRI scale levels. I only want the ESRI map to be visible when you first get to the sight, once you zoom in once...I want it gone and only my "basemap" mxd layers showing. This is really only being done so that the map screen is not mostly white with only a county showing. I just think it looks bland and plain. So i am just trying to fill the screen with background reference data around the county itself. It would also be nice to have the shade and color from the ESRI service instead of just my plain white county with a few highways and cities labeled, which also look dull to me. I am trying to re-cache my basemap mxd again at the one level I need displayed, hope this works. Thanks for all the input!

Mike,

The forum condenses urls by default. the actually url is not changed but what is displayed is a condensed version. As far as code insert look at this attachment.

Code_Insert.jpg

MikeHargreaves

Not sure why it cuts up the URL - but the work that was cut up is flexviewer.

Also, can someone tell me how to insert code properly? Thanks.

MikeHargreaves

I'm not sure what your cross section layers are, but they sound like they should be an operational layer. My sight sounds somewhat similar. I'm using aerials, elevation and hillshade as my base layer choices. I've also added into the basemaps section a dummy layer that allows me not to have a basemap layer at all:

<layer label="No Base" type="tiled" visible="true" alpha="1"
url="http://agsmaps.ci.santa-rosa.ca.us//ArcGIS/rest/services/xyz/MapServer"/>

In addition, I have another layer that folks often add to the basemaps that has streets and boundaries and the like. I've put that in the operationallayers section instead, that way it can be turned on, on top of a different basemap. I do the same with labels. I default the map to have no basemap, but I have the streets and labels turned on. If you would like to check it out, here is a link:

http://agsmaps.ci.santa-rosa.ca.us/flexviewer/index.html

ToddZimmerman

Your base map shouldn't be listed under OperationalLayers. Each map service should only be in one place or the other, not both.
