Thanks for reply, peter, Looking forward to it. 10.2 will support both Pleiades 1A and 1B as well as SPOT6 products.... On Georeferencing tool (with RPCs) used to refine the accuracy with GCPs, do you referred to 10.1 SP2? Will the tool be integrated into (or work directly) inside MD? ... As with 10.1 RPCs are directly supported and georeferencing can be refined using the georeferencing tools in which control points can be used. Regards,

Team, It seems that MD does not support the RPCs of the new sensor Pleiades 1A & 1B; and wondering if MD can support new sensor models quickly, including Pleiades 1A (2011) and Pleiades 1B (2012). Recently, have been evaluating the Pleiades & SPOT 6 imagery. Initially, the Pleiades twin sensors give very impressive features: [INDENT]1. Pleiades twins are quickly responses to customer needs (twice-daily revisit) against GeoEye-1; 2. larger coverage/strips, similar to 2.5-m SPOT 5; 3. Able to provide similar information for visualization and extraction (like GeoEye-1), which is much better than 1-m IKONOS (hard to retrieve information); and also easier image processing & interpretation (against SPOT-5) [/INDENT] For more on Pleiades twins at http://www.astrium-geo.com/pleiades/ and on SPOT 6 at http://www.astrium-geo.com/en/147-spot-6-7 Most likely, it would be still a challenge to ortho-rectify Pleiades images (without combing GCPs) to meet the operational requirments of accuracy, if still only considering RPCs alone.

Thanks, Cody, The scripts like �??MDCS�?? (http://bit.ly/Owa2D6 ) under the ArcGIS Image Management Workflows (http://bit.ly/Z7kbNC) looks only available to the ArcGIS Online 'business' accounts. Is it correct? Do we have any other ways to get it? Regards, Larry @ Aramco

Hi, team Is there any effective IT way or ESRI-ready tool (script) for us to know the traffic at ArcGIS Server 10.1 (saying, at the port 6080 or 6443) and see who access to this server? Basically, we want to answer the following questions via statistics? ??? How many users access (weekly, monthly, yearly) ??? Who visited Many thanks in advance, larry at Aramco

Matt, On CGA, the example of Philadelphia 2012 confuses me. Is it right example for this idea? Here, I have quick Q for consulting (sorry about those): Where are the GIS points for tree to �??grow�?? in the example CE? It looks there is no GIS points in this example. If used the attachment of SHP, how to organize the point SHP in new CE project and then make use of this example code?

Matt, For learning the powers of CE, can you pls instruct to implement the following idea? 1. Steps to import and organize the SHP (saying, Trees.shp) into CE project (the attachment) where there is a 'field' for different kinds of tree (1, 2, or 3), which individually represents �??pine, oak, or ash tree�??; 2. Code trees�?? rule (with the field 'TreeHeight' & �??TreeType�??) Regards and many thanks, Here's a cool simple approach to create some variating building volumes, which can grow thinner from floor to floor.

Matt, ... http://forums.arcgis.com/threads/76669-Shapes-VS.-Models-VS.-MultiPatch It is helpful. Of course, my issue is reffered to '3D model' as multipatch (textured 3D model/shapes, if no distinction). From your post, I see the statement "MultiPatch IMPORT into CE : If a MultiPatch is imported into a CE scene via gdb, Shapes are created.". Does it mean that CE does not import 'textures' of 3D model/shapes into an 'existing' CE project or CE scene? If true, it could be an issue to CE, which should be improved in the new release of CE. Isn't it?

Many thanks for clarifications, Matt. .... CityEngine supports assets ( e.g. .dae ) which have 1 or multiple textures already assigned to it ( with correct UVs ). ... From our practice, when �??initially�?? importing 3D model with �??shape textures�?? (by photos) from geodatabase (or KMZ) into �??fresh�?? CE project and then importing others (image textures, SHP, etc.), those �??shape textures�?? can be kept 'AS IS' within 3D model. However, when importing 3D model with �??shape textures�?? into an 'existing' CE project, which already has many 3D shapes and imagery textures, those �??shape textures�?? (by photos) are lost. Is this behavior normal? If not, any advices to avoid or fix in CE 2012.1?

... the Identify tool still returns a pixel value of zero. ... From 'imagery processing' perspective, most likely, pixel values of zero inside the 'processed' raster imagery are not valid (except for DEM, and a few of cases for specific purposes). In other word, the pixel values in �??processed�?? panchromatic imagery should be ranged from 1 to 254 for 8-bit products. (Of course, 1-255 are widely acceptable). For RGB imagery, similarly, the pixel values (0, 0, 0) also should be avoided in the deliverables of 'processed' imagery. In fact, through this kind of inspection onto �??processed�?? imagery inside ArcGIS, it has been became one of the easiest practices as common QA/QC exercises in operation (such as, to avoid voids and black edge, etc.).

Hello. ... The circled areas in the attached image should not display as NoData as there is imagery here. ... [ATTACH=CONFIG]20749[/ATTACH] Firstly, identify the DN (pixel values) inside the circled areas by �??Identity�?? tool and see if those are �??0�?? value. If yes, that indicates that both the background and circled areas in the MrSID imagery share same value (�??0�??) by default in ArcGIS, even though those are different from imagery perspective. So, use one of the following options, so that ArcGIS can properly differentiate those circled areas of the MrSID imagery against the background: 1. Under �??Symbology�?? of the Layer Properties in ArcGIS, check �??Display Background Value�?? and setup any color (saying, red); meanwhile, change default color in �??Display NoData�?? to other (saying, black). And then see if it works. If not, use the following solution to ensure that this issue will be solved permernently; 2. Import this MrSID into ERDAS (MrSID licensed) and then reprocess it via the Histogram/LUT. Make sure that the DN values inside those circled areas are over �??0�?? (saying, �??1�??) and then save as new image in IMG (or, export into MrSID again, if preferable)

Greeting, all, Thanks for above discussions. We need those *.DAE models georeferenced for sure. Does anyone have any practice on how effectively to georeference those DAE files in ArcGIS 10 or 10.1 (ArcGlobe or ArcScene), �??with�?? those assocciated KMZ files? Or can we spatially adjust those *.DAE models, 'with' those location-enabled footprints from geodatabase 'directly' in ArcGIS 10.1? I am wondering why one (KMZ) has georeferenced information and another (DAE) is not. (In fact, both of those *.DAE and KMZ files are saved/ exported from same SketchUp projects (7, 😎 at same time). In other word, do we have any 'efficient' way to ensure all having georeferenced information during Exporting in SketchUp? If not, what causes (standard Collada 1.4)? Regards,

It looks good. Also, do you know if the two issues in the attachment are solved or available in 2012? Here's what I found on their blog. Looks like a new version by June. Some highlights of the upcoming release include: Native 64-bit support Highly portable �?? no install needed, can run completely off a thumb drive Integrated ArcGIS Online and Portal for ArcGIS search capabilities Updated ArcGIS Online web map support Many presentation enhancements, including audio, new transition options, better slide handling, and more. Display attribute table for feature layers Built-in line and polygon buffering Custom address geocoding support (10.1 geocoding packages) More�?� ArcGIS Explorer Desktop 2012 will be released in conjunction with the final release of ArcGIS 10.1.
