Picked this link up from Digg.com. Another nifty Google Maps interface.
OK, it is late I probably shouldn’t blog just before sleep, but I figured I would forget this link in the morning. The Digg submission linked below is a person who found clouds on the aerial imagery when they were on Google Maps. They don’t say whether they think this is good or bad, but being sleepy I am going to assume they were incredulous at the least. My problem with this? One contracts for US government agencies the company flying the data is required to have the images be 85-90% cloud free for an acceptable product…satellite imagery, you hope for 60-70% cloud free if you are looking for something in a certain time range (if you aren’t picky about when it is usually easier to find cloud free data). So a couple of clouds in a commercial product that has little to no orthorectification (though pretty good georectification) isn’t something I would find note worthy.
Well that isn’t true, it gave me a chance to share you lovely people why a cloud isn’t a big deal.
So follow the link to see the cloud (it is quite a nice cloud in fact). Clouds on Google Maps
Continuing my obsession is an article regarding NASA’s new instrument for capturing the martian surface. Please not that they talk about the number of pixels the instrument will collect at a time, but not what the spatial resolution of each pixel will be, which is actually more important for the end-user. The other important information, that could help us determine the spatial resolution of the imagery, is anticipated scale.
An interesting perspective on how a Google Maps news link might appear.
Frank will be joining us to offer a column on the state of web mapping and any other matters he thinks are relevant to the topic of Geography and geospatial technologies.
Here is a follow-up on the Australian security issue…now it isn’t as significant apparently.
An interesting article regarding Amazon’s street imaging in urban areas.
Following the ever growing stream on the current WebMapping boom, James, over at Spatially Adjusted, had some thoughts to share.
While the use of GPS to track and route vehicles for corporations such as UPS and FedEx is nothing, it is always nice to see these technologies filter down to an everyday use.
This article from news.com.au that I picked up from SlashDot ties into a topic that we covered in the podcast this week…the concern over what high resolution aerial/satellite imagery is appropriate to release and what is not. The Australian Nuclear Science and Technology Organisation is concerned about the easy access to information, in this case imagery, about sites that are considered sensitive. Check out the full article…or wait for next weeks podcast
