Announcing the Next Generation of ArcGIS Ideas in the Esri Community on GeoNet!

As previously mentioned, we are excited to announce that the ArcGIS Ideas site has a new home in the Esri Community on GeoNet! The move is set to happen on the evening of May 26th, 2016 so mark your calendars!

Your existing ideas and comments will be seamlessly integrated into the ArcGIS Ideas Space and can be accessed via the existing URL: http://ideas.arcgis.com. A link will also be added to the global banner which appears throughout all of GeoNet.

Much like the old ArcGIS Ideas site, the new home page will feature the most recent and top ideas that have been submitted and more.  The GeoNet platform also offers new and exciting features. Here are the top three to look forward to in the ArcGIS Ideas Space:

Updated Categories – Ideas will be organized based on our current products and capabilities, to make submitting and browsing easier.

Revamped Statuses – New statuses will be implemented to improve the visibility of the life cycle of an idea. They will describe the varying stages of an idea’s life from the time it’s submitted to the time it’s reviewed, considered, and potentially implemented, etc.

Collaboration Tools – It will be possible to @mention people, places and content across the Esri Community to directly link an idea or comment to another entity in Geonet. Including additional authors on your idea will also be possible to foster collaboration with your peers.

Keep an eye out for additional blogs and content to get better acquainted with this exciting new space. On the day of the move, May 26th, all existing content on the current ArcGIS Ideas site will be read-only. Following this date, you will be redirected to the Esri Community when accessing http://ideas.arcgis.com.

Please continue to share your ideas and feedback with us. We want to hear from you and we’re thrilled about this opportunity to introduce ArcGIS Ideas to the Esri Community!

Support.esri.com Beta Launch!

It’s here! We have released the beta version of the upcoming Support website redesign. This is an exciting change that enhances the current capabilities of the web site, improves the organization of Support content, and modernizes the way in which you interact with Esri Support.

This beta site is available as a preview of the new navigation, functionality, and design for Esri’s online support engagements. Please note that we are still completing some of the final content migration tasks, and there are a number of known issues that are being actively addressed by our development team – after all, beta does not mean “complete!” In the upcoming weeks, we will be fine-tuning the search results, product content, and downloads. During this period, the current Support website will continue to provide access to both assisted and self-support resources, so you can still contact Support if need be.

Product-Centric Navigation

A big difference from the previous website design is the new site’s product-centric navigation. Rather than separating the content by type (technical articles, web help, downloads, etc.) via several links on our current front page, the content on our new site is grouped by product. Instead of having to look in three different locations to view the content we have for our entire product library, you can select your product and version, and then you’ll get all types of content related only to that product and version. We are simply organizing the content in a way so that you won’t have to look at stuff that doesn’t apply to you.

Product headings are listed at the top of the page, and go across from left to right. If you are looking for older content, or if you do not believe it fits any of the five major categories (Desktop, Server, Online, Developers, Apps and Mobile), check the “More Products” section, or use the global search bar at the top of the home page.

Solution Finder

Another new feature is the Solution Finder, which is located on every Product page. The idea is to “find solutions” to your questions. When you have identified a product, the Solution Finder sorts our knowledge base content by topic category. For example, if you need information about the Address Locator, or you have general geocoding questions, it would be best to check Map Authoring and Visualization > Geocoding for potential solutions.

If you are unsure which category to check, you can also search the entirety of the content indexed by Solution Finder by using the Search bar.

There are several different categories to choose from, each covering a wide variety of topics related to GIS and Esri products. Kind of like an index at a library - check it out!

This web site has other new pages and web features, some of which we will discuss in future blog posts. We are excited to share this website with you, and encourage you to keep your eye on our blog channel for further developments, updates, and information related to the new Support website.

If you have any formal feedback or questions regarding the Beta Support website, please contact This email address is being protected from spambots. You need JavaScript enabled to view it.. Thank you!

Preparing Data for CityEngine

Looking for a way to model your city in 3D? Look no further! To create a 3D model of a real world city in CityEngine that can be used for city planning, modeling of 3D phenomena, or even in 3D gaming environments, all you need is a DEM, streets data, and building footprints.

Before you bring your GIS data into CityEngine, however, there is some data preparation involved. Here, we review key information you need to know before getting started.

Common Terms used in CityEngine

Terrain = Digital Elevation Model (DEM)

Texture = Aerial Image or image for building facades

Graph = Streets

Lot = Building Footprint

Terrain and Texture

The first step is to gather your terrain and texture to overlay on top of the terrain. If you do not have a DEM, you can download one from the USGS. For terrains, 16-bit and 32-bit images with a maximum size of 4000 by 4000 pixels are supported. In order to verify the bit depth and number of rows/columns of an image, you can load it into ArcMap and check the information on the Source tab of the Raster Layer Properties.

Another key part of preparing the DEM and Aerial Image is to ensure that they have the same extent. This can be done in ArcMap by drawing a polygon graphic for the project area and running the Clip tool on the raster to clip both the terrain and texture to the same extent, or exporting the raster with the selected graphics as the clipping extent.

Another common issue is that the image has four or more bands. When this is the case, the aerial image will appear washed out. To resolve this issue, use the Make Raster Layer Tool in ArcMap and create a raster with three or less bands. The output from this tool will be temporary so it must be exported out in order to bring it into CityEngine.

Streets and Buildings

The second step is to obtain feature data for streets and buildings. Commonly used street formats include shapefiles, geodatabases, KML, and OpenStreetMap (OSM).  When you import the street data into CityEngine, sometimes there are messy intersections and merged nodes. We recommend using the Cleanup Graph tool to clean up these intersections, or manually edit the streets. If there are street segments that extend beyond the area of interest, use the selection tool to select the segments and delete them. Streets may also appear below the DEM - this can be rectified by running the Align Shape To Terrain tool, or manually raising the streets.

Additionally, OSM contains options for importing building footprints. With CityEngine you have the ability to generate your own lots, use your own data, or use those provided by a third party, such as OSM. An important distinction is that lots in CityEngine can represent the entire legal lot for a parcel, the building footprint, or lots with building footprints. When importing an OSM file, check the Highways and Buildings in order to import both the streets and the building footprints. Once the streets are imported they may be offset from the terrain and this can be remedied by using the Align Graph to Terrain tool in CityEngine. .

Adding streets and building footprints.

Projection

Once you have the terrain, texture, streets, and building data, the next step in data preparation is ensuring that your data is correctly projected. It is good practice to ensure that all layers are in the same Projected Coordinate System. CityEngine does not support Geographic Coordinate Systems such as WGS 1984 or NAD 1983 for the scene coordinate system, so the scene will need to be in a Projected Coordinate system. Additonally, CityEngine can only apply datum transformations for vector data. For terrains and textures you must ensure the datum matches the datum used in the scene. We recommend bringing the data into ArcMap prior to importing into CityEngine to ensure that everything lines up correctly and has the same projection. If you are downloading your data from OpenStreetMap, the OSM data format is not supported by ArcMap, so CityEngine will reproject the data to the scene projection and perform a datum transformation, if necessary (OSM uses the WGS 1984 Geographic Coordinate System.)

CGA rules

Once all data has been added to your scene, you can start the actual modeling. CityEngine uses CGA (Computer Generated Architecture) rules to programmatically generate buildings from footprints or lots. These rules determine the geometry of each building created (has four walls and a roof) as well as color, textures, height, number of floors, roof shape, and so forth. CGA rules usually have an element of randomness so that the city has a natural and varied appearance. For example, a rule could be created that all buildings are between 30 and 50 feet high and have roofs with pitches between 20 and 30 degrees.

Writing CGA rule files can be an involved process, but fortunately there are a number of pre-existing CGA rule files available to get you started:

The Buildings_From_Footprints.cga file found in the Esri.lib project (installed with CGA.) A number of CityEngine projects with CGA files have been made available for public use and are available on ArcGIS Online by the CityEngine team here. Esri also provides a number of tutorials and examples, most of which come with pre-made CGA files which can be copied and modified, and these can be found here.

If you are interested in writing your own CGA files, check out this tutorial as well as the CityEngine manual.

3D models

If you have areas of the city with distinct architecture or landmark buildings, you may want to consider adding pre-constructed 3D models. These models can be created in one of the many 3D modeling software programs, such as Blender or 3ds Max, or purchased on a 3D warehouse such as 3D Warehouse or Turbo Squid. Just be sure that the models are in one of the supported formats (multipatch, DAE, FBX, KML, KMZ, and OBJ). Most 3D models are not created in projected space, but once they are added to CityEngine they can be scaled, rotated, and positioned as needed.

Adding 3-D models to the scene

How big can I go?

One question that we are frequently asked is “How big of a city can I have in CityEngine?”

There is no hard and fast rule for this, as it depends on the number of shapes, the complexity of the models, the number of textures, as well as your system memory and graphics card. You can check the system requirements and recommendations to see if your system can support CityEngine.

Remember that CityEngine is a modeling tool and not a visualization tool. When you are testing your rule files, it is generally good practice to only generate a portion of your city. This will improve performance both for the model generation and drawing. Then, when you have finalized the rules, you can generate all the models and export it to several different file formats (such as multipatch, DAE, FBX, KML/KMZ, OBJ, CityEngine Web Scene 3ws, Renderman RIB, and e-on Vue VOB) with the expectation that this may take some time if your city is very large.

Once the data is prepared, creating your model is just a question of bringing the data into a scene and applying the rule files. From there, you can refine your model by improving the CGA rule files, growing new streets and parcels to plan new developments, or creating a complex city with different rules for different sections of the city.
