A Tale of Two Pixels: Nodata and Transparency in GeoExpress

GeoExpress is a software package that provides image compression technology for converting raw imagery into the compressed MrSID format. Not all MrSID files are created equally, however, which makes understanding the differences between them very important. MrSID Generation 3 (MG3) files are a legacy format still used by many GIS applications. MrSID Generation 4 (MG4) is the newest file format available in GeoExpress. MG4 files offer many benefits when using…

Why are Pixels Missing in my Image?

When I convert raw data to a MrSID file there are many areas within the image that are the wrong color. Here is the raw image: And here is the compressed MrSID: Some explanation of how GeoExpress and ArcMap handle nodata is in order. To learn more about missing pixels in your MrSID image, visit the LizardTech Knowledge Base. To find out more about GeoExpress and MrSID, click here.

MrSID Compression and Despeckling

Despeckling in MrSID Compressed Images

Speckling artifacts happen because compressing images to MrSID at high compression ratios requires approximating colors. In other words, “black” becomes “almost black.” While the human eye doesn’t ordinarily notice the difference, this can make it difficult (not to mention ugly) to mosaic images together. Speckling also happens with other background colors depending on the nodata value. To learn more about despeckling and why this happens, click here to visit the…

Transportation Agencies Compress, Manipulate and Serve Immense Data Sets with LizardTech Products

The agencies responsible for building and maintaining transportation infrastructure are difficult to define. There are vast differences from agency to agency in terms of reliance on design engineers and construction contractors. There is no ‘typical’ transportation department. A quick review of our LizardTech transportation clients in the US and Canada finds most reside at the state and provincial levels. Some deal only with roads and highways, while others manage maritime…

Pain Points Survey Blog #2: How Do You Handle Large Data Volumes?

LizardTech conducted an industry survey at the Esri User Conference in July and online in August. If you’re wondering how your industry peers are using, compressing, accessing and storing all types of raster data, refer to this blog over the next few months for an overview of the survey results. Handling, managing and storing large volumes of data are major concerns throughout the geospatial industry. As sensors and scanners have…
