My new peer-reviewed article titled “Automated delineation of karst sinkholes from LiDAR-derived digital elevation models” has been published in the latest issue of Geomorphology. You can download a free online copy using this link: http://authors.elsevier.com/a/1T3d9_,Oh6mAl8 (expires on July 8, 2016). In this paper, we present a localized contour tree method for automated extraction of sinkholes in karst landscapes. The study area was Fillmore County in southeastern Minnesota, USA. See some figures below:
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of the instruments on NASA’s Terra satellite. Although it is a NASA satellite, the instrument belongs to Japan’s Ministry of Economy, Trade and Industry (METI). The instrument was launched in 1999 and has captured more than 2.95 million individual scenes since then. On the first of April this year NASA announced that the full catalogue of imagery is being made available to the public at no cost. The instrument, amongst other things, takes stereoscopic images that enables it to calculate altitudes albeit rather low resolution. The elevation data has always been available to the public at no cost.
Mt. Etna, when it erupted in July 2001. The full resolution image and description can be found here.
This image shows the 3D capabilities of ASTER. The full resolution image and description can be found here.
To access the full database of imagery, you can use the MADAS (METI AIST Data Archive System). A really nice feature is that it allows you to download the images as network-linked KML files.
The imagery has a similar resolution to Landsat imagery (approximately 30 m per pixel), so is really only suitable for viewing large scale phenomena. As with Landsat imagery its best use would be to see current events before other satellite imagery becomes available. In December last year we used Landsat imagery to look at the scar made by a tornado near Holly Springs, Mississippi. We found it relatively easy to find an ASTER image of the same region captured on March 28th, 2016, and the scar is still visible. Download this KML file to view it in Google Earth.
The image only covers a small part of the tornado’s track.
Drone2Map for ArcGIS, released on February 24 by Esri, is a stand-alone desktop app for processing imagery collected by drones. Check out the Drone2Map FAQ and an interesting presentation (Working With Drone Data In ArcGIS) by Tony Mason of Esri. Interested users can visit esri.com/drone2map for more information.
Q: Is Drone2Map for ArcGIS going to be an ArcGIS Extension?
A: No. It is a stand-alone 64-bit Windows desktop app that will run alongside ArcMap and ArcGIS Pro.
Q: What does Drone2Map for ArcGIS do?
A: Drone2Map for ArcGIS is a desktop app that turns raw still imagery from drones into stunning information products in ArcGIS. Now, with drone hardware becoming more accessible, you can create 2D and 3D maps of features and areas.
Q: Can Drone2Map for ArcGIS be used to make 3D models?
A: Yes, Drone2Map for ArcGIS will produce 3D colorized point clouds in LAS format as well as 3D textured meshes for use in ArcGIS Desktop and Web Apps.
Q: Does the Drone2Map for ArcGIS work only with a specific type of drone?
A: Drone2Map for ArcGIS is designed to be generic for all drones. What is important is that the drone collects certain types of metadata. At a very minimum, this metadata needs to include Latitude, Longitude, and Altitude. The addition of orientation, focal length and pixel size of the sensor will greatly improve results. Many commercially available drones have this capability and automatically add this information to the image metadata.
This might be of interest to some of you teaching large enrollment courses and using scantrons for quizzes/exams. I developed a script using R programming language to automatically extract scores from ITS test scoring results and upload the grades to Blackboard.
The script needs two CSV format input files: the student info file from Blackboard (Full Grade Center -> Work Offline – Download) and the ITS test scoring results (convert the Excel file to CSV). It takes less than one second to get the results.
Feel free to let me know if you have any questions.
BBfile <- file.choose() #”roster.csv” ### The file downloaded from Blackboard
ITSfile <- file.choose() #”result.csv” ### The file received from ITS scantron results
# BBfile <- “roster.csv”
# ITSfile <- “result.csv”
output <- “score.csv”
scale.factor <- 1 ### scale factor multiplied by the scantron results.
### Extract students’ fullname from Blackboard roster
roster <- read.csv(BBfile,header = TRUE,stringsAsFactors = FALSE)
roster$firstname = as.character(lapply(strsplit(as.character(roster$First.Name), split=” “), “[“, 1))
roster$fullname <- tolower(paste(roster$Last.Name,roster$firstname,sep=””))
### read the ITS results
df <- read.csv(ITSfile,stringsAsFactors = FALSE)
df <- df[nchar(gsub(” “,””,df$X))>0,]
df <- df[!is.na(as.numeric(df$X.5)),c(“X”,”X.2″)]
colnames(df) <- c(“Name”,”Score”)
df$Score <- as.numeric(df$Score) * scale.factor
### extract student names from ITS results
lastname <- as.character(lapply(strsplit(as.character(df$Name), split=” “), “[“, 1))
firstname <- as.character(lapply(strsplit(as.character(df$Name), split=” “), “[“, 2))
df$fullname <- tolower(paste(lastname,firstname,sep = “”))
### match student names from Blackboard and ITS
m.x <- merge(roster,df,by = “fullname”,all.x = TRUE)
m.x$raw <- m.x$Score / scale.factor
### save the results to csv file
write.csv(m.x,output,na = “”,row.names = FALSE)
m.y <- merge(roster,df,by = “fullname”,all.x = TRUE,all.y = TRUE)
m.y.sub <- m.y[is.na(m.y$Last.Name), ]
score <- read.csv(output,header = TRUE,stringsAsFactors = FALSE)
If you want free satellite data, there’s no better way to do it then to follow this incredibly useful guide. Ranked from top to lower tier, here are your go-to free satellite imagery sources. Take a look at our list of eyes from the sky.
1 USGS Earth Explorer – Unlock the Power of Landsat and More
Whether you live in the United States, in the Arctic circle or an obscure country like Transnistria, we can all appreciate the abundance of data theUSGS Earth Explorer has to offer.
From no data to hyperspectral data, USGS is the undisputed world champion of free satellite data providers. Here’s why:
- Access to Landsat satellite data – a legacy that goes unmatched. 40-years of history of our Earth with consistent spectral bands.
- Vertically position yourself with NASA’s ASTER and Shuttle Radar Topography Missions global Digital Elevation Models.
- Gain full access to NASA’s Land Data Products and Services including Hyperion’s hyperspectral data, MODIS & AVHRR land surface reflectance and disperse Radar data.
We sound like a broken record. But USGS Earth Explorer is a world class source of free satellite data. Regardless where you live, you NEED to look at the USGS Earth Explorer.
2 ESA’s Sentinel Mission – New Leader in Free High Resolution Data?
I just started exploring Sentinel-1 SAR data for my research on wetlands and water resources. Here are some useful resources I found:
About the Sentinel-1 mission:

Synthetic Aperture Radar: Of Bats and Flying Pianos:
- An amusing introduction to radar remote sensing from satellites, with the concept of “range Doppler” image formation described using entertaining audio-video animations.
For those who are interested in using the Sentinel-1 and Sentinel-2 Satellite Data from the European Space Agency’s Copernicus Programme, please check out this blog at http://gisgeography.com/how-to-download-sentinel-satellite-data/. Note that Sentinel 2A multispectral data has a 10-m spatial resolution, which is much better than the Landsat 8 with 30-m resolution.
What are the Spectral Bands of Sentinel 2A and 2B?
The spectral and spatial resolution of Sentinel 2A are listed below. There are 13 bands in total. Four spectral bands have a 10 meter resolution. Six bands have a 20 meter resolution. And the remaining 3 have a spatial resolution of 60 meters.
Here are the spectral band details for Sentinel 2A:
Source: SENTINEL-2 Spatial Resolution
Each single satellite revisit time is 10 days. Because there are two satellites (Sentinel 2A and 2B), this means it has a combined constellation revisit of 5 days.
