From The General Manager Jim White discusses LizardTech's recent geospatial survey and its very promising results.

Geospatial

LizardTech Spatial Express, a plug-in for Oracle Spatial that adds support for storing MrSID and JPEG 2000 imagery in a database, has been well received by our partners and customers. Finally, users are able to store large raster datasets in their databases, just like they've been doing for years with feature data. However, because up until recently it's been impossible to store large raster images in a database, some people still wonder why they shouldn't just continue storing images on a file system.

This is understandable, of course, since storing even small geospatial images can take up lots of space and have historically been unwieldy to work with in a database. Databases have traditionally stored images as BLOBs (Binary Large OBjects), which essentially puts all of the image data into one record of a database. Because of this, even if you wanted to view only a tiny piece of a very large image, you had to decode the entire dataset, which takes up lots of processor resources, lots of memory, and most regrettably: lots of time. Workarounds to this have been available for some time such as pyramiding, where images are pre-processed at different magnification levels and then split apart into individual tiles. This means that the portion of the image you want to view can be retrieved quickly, but it also means that you must now store all of those individual tiles in your database, which again takes up a lot of space. Furthermore, the amount of time needed to generate these pyramids can be immense, sometimes weeks or even months.

Spatial Express solves this problem by customizing the database so that images are stored natively in either the industry standard MrSID or ISO standard JPEG 2000 format. Because Spatial Express uses the native wavelets for storage, the imagery no longer has to be treated as a BLOB. Every scene, whether it's 200 pixels square or 20,000 pixels square, can be viewed quickly and easily, even coming from source images that are hundreds of gigabytes in size, because Spatial Express just decodes the pixels you need. Of course, since the images are stored as MrSID and JPEG 2000, they don't take up much space, typically only 1/20th of their original size. Best of all, there is no need to pyramid the data, so you can load your imagery in quickly. If your database has Spatial Express installed, you can even use your GeoExpress software to load your images into your database as part of your encoding workflow!

Customer Wins and Case Studies

This quarter we added another customer success story showcasing the benefits our geospatial products bring to our valued customers.

The Québec Ministry of Sustainable Development, Environment and Parks promotes sustainable development while protecting natural ecosystems. The Ministry annually receives 10,000 aerial images of provincial territory in color and greyscale, which it uses for ecological analyses. The Ministry installed LizardTech GeoExpress to convert GeoTIFFs to industry standard MrSID format and Express Server to distribute the imagery among its offices and field personnel for use as image layers in ArcMap and WMS-enabled web applications. Now, personnel anywhere can quickly view any of the Ministry's image data from one central, easily updated repository. You can read the entire case study by visiting our case study page.

We would also like to share with you recently added clients to our ever expanding customer base catalog:

• Petroleum Geographics Mapping
• Digital Globe, Inc.

When you purchase 1 copy of a GeoExpress encoding bundle or GeoExpress Unlimited, you will receive a FREE copy of GeoExpress Tools (a $1,500 value) OR a FREE floating license (a $1,000 value). As with everything else in GeoExpress, the choice is yours! To take advantage of this limited offer, contact your sales representative at 1-866-725-5211 or 206-652-5211 or geosales@lizardtech.com.

Tips and Tricks

This is a new segment of our quarterly newsletter. Each quarter we'll offer a practical tidbit about how to perform a certain task or achieve a certain result using one of our software products - a tip or trick you might not be aware of that we hope you'll find useful.

This quarter, save time by using the Optimize feature in GeoExpress. Here's how:

The Optimize feature in GeoExpress offers special options for repurposing existing MrSID Generation 3 (MG3) files quickly. If you have an existing MG3 image you can use the optimizer to save time when recompressing, resampling, cropping, and using area-of-interest encoding.

Optimizations can be done very quickly because they are performed in "wavelet space" on already encoded images that remain encoded. The time involved in decompressing an image to alter it and then reencoding it is eliminated.

To use the optimizer, click the Optimize tab on the left, then select Project > Add MrSID image to optimize.

IMPORTANT: These features are available for flat files and for composite MrSID images provided that they were originally encoded as 'optimizable' (encoded with the Optimizable checkbox selected).
