Bentley Systems’ Performance for 2011
Wednesday, March 14th, 2012Bentley Systems CEO Greg Bentley gave Bentley Systems’ second annual Corporate Update in a conference call last week.
“Bentley Systems’ revenue on an historical gap basis grew 10% to a record $523 million,” said Bentley. Asia was a major driver of this growth, increasing to comprise 19% of total revenue from 16% in 2010.
The software subscription business model accounts for 17% of revenues in 2011. The company’s resilient subscription revenues have enabled them to fully recover from the downturn faster than their competitors and software peers with less volatility and with greater visibility into this coming year.
The subscription business model also benefits the user organization that had invested in their future reuse of infrastructure information modeling through Bentley software. The relative lack of volatility in Bentley Systems’ revenues is good for the company’s stability and reliability and that is, along with subscription elimination of cost barriers for technology adoption and improvement, is good for user organizations.
“Change matters” viewer from Esri displays Vegas sprawl
Tuesday, March 13th, 2012The Change Matters viewer from Esri can show how your area has changed over a given time period, say for instance, from 1988 to 1990. Las Vegas is known for its phenomenal sprawl over the past four decades. Time-lapseimages from the Landsat earth monitoring satellites reveal in false-color, multispectral imagery how urban sprawl has stretched out from Nevada’s “Sin City” over the past four decades.
This latest video was posted by NASA in honor of the 28th anniversary of Landsat 5’s launch on March 1, but the pictures actually go back to 1972, when the Landsat program began.
RapidEye imagery used for MALAREO project in southern Africa
Tuesday, March 13th, 2012RapidEye announced that its imagery is being used by the MALAREO project help with malaria control programs in countries in southern Africa. Basically, the satellite is mapping the habitats of mosquitoes, which are generally considered malaria risk area. Funded by the European Commission under FP7, the MALAREO project is a mixed European-African consortium that embodies many years of malaria control expertise with the Global Monitoring for Environment and Security (GMES) EO Capacity.
The MALAREO study area in South Africa, Swaziland and Mozambique is approximately 25,000 square kilometers that RapidEye data provided via the EC/ESA GMES Space Component Data Access (GSC-DA). Over five different days between July 18 and November 10, 2011, the data was gathered with total cloud cover of less than one percent. RSS – Remote Sensing Solutions GmbH, partner in the project consortium, is responsible for data processing and the development of Earth Observation (EO) products.
