(09/12/22) ArcGis Earth Introduction and Creation of Mapping Missions

 ArcGis allows for a more developed understanding of spatial data and features one can assess before or after flying a mission. Many different data layers can be applied to a certain landscape, however the lab focused on the different National Agricultural Imagery Program (NAIP) maps and color schemes seen pictured below.

Normalized Difference Vegetation Index (NDVI) of Purdue Campus


Notice the color spectrum difference based on vegetation health and density. Red/orange plots being dried crop fields whereas darker dense green being forests or healthy vegetation fields.


NDVI: Color Infrared of Purdue Campus

Take note of the different color scale and thus differing features that stand out. Blue/gray areas are primarily man-made concrete or glass structures. The red/magenta colors represent natural vegetated areas. The darker the red, often the healthier the vegetation.


Mapping Mission Planning with Google Earth and Pix4D Capture

Using Google Earth and the Pix4D Capture platform with connection to a Mavic M300 controller, flight crews created and saved various flight plans that all contained different parameters. Those parameters being different overlap, sensors, and flight time.

Zenmuse P1 H20/H20T IR Sensor - ET: 1 h 2 m 34 s. 11.11cm/pixel (original picture of area)

Zenmuse P1 H20/H20T WIDE - ET: 26 m 15 s. 4.31cm/pixel
Zenmuse P1 35mm Sensor: ET - 34 m 28 s. 1.57cm/pixel

Zenmuse P1 24mm Sensor: ET - 23 m 39 s. 2.29 cm/pixel


Micasense RedEdge w/ customized lens - ET: 24 m 6 s. 6.17cm/pixel


Sony A7R sensor w/ customized lens - ET: 42 m 28 s. 3.33cm/pixel



All different sensors and overlaps have varying estimated mission times and GSDs based on what is required minimally to collect data based on location and flight overlap.

Pix4D Processing and Map Making with Ground Control Points

Image
 The usage of ground control points (GCPs) can be extremely useful when processing data and creating orthomosaic images of an area flown for data analysis. Below I have two instances of processing using GCPs, both of the Purdue Wildlife Area (PWA), and both used for independent and various analyses.  Once in Pix4D, the GCP data collected is set into a file location, and on a spreadsheet, the various figures collected from the GCP during the flight are brought and inserted into Pix4D to begin processing. Initial processing then is selected and let run completely. Make sure correct projection and GCP locations are used before processing is started. Processing varies in time length, but after completion a post processing evaluation should be done.  Next initial processing should be unselected and the next two steps should be run, that being point cloud mesh and lastly the creation of a DSM and orthomosaic model. Once processing is done, locate each GCP location and make sure...

Analyzing Attribute Data: Spatial Joins, Kernel Density, and Hotspots

Image
Continuing on using some of the same airmen data from the last portfolio post, the objective of this project was to continue to develop spatial joining and analysis of data to develop a visual and statistical density and distribution. Before beginning, once again, the correct projection must be used in order to maintain consistent and correct visual and distributable information. The projection used for this project was Lambert Conformal Conic, a visually more correct map to the spherical shape of the Earth. The continental U.S. was selected using the 'feature to feature' tool within the geoprocessing toolbox. Next the state of Indiana was queried out using the select tool with 'intersect' being selected as well. A Kernel density of the airmen within Indiana was then ran.  Above is the airmen data visualized by being overlain onto a correct projection of the state of Indiana using the Kernel density tool. Notice where the greatest densities lie, that being Indianapolis ...

Summer 2024: Work at ACRE with Purdue Civil Engineering and Agronomy Department

Image
This past summer I had the privilege to work as a UAS pilot at Purdue University's ACRE (Agronomy Center for Research and Education) facility and the subsequent fields that surrounded the area. The fields varied in differing experiments being conducted and monitored on corn, soybean, and sorghum. My role was to continually fly and monitor different fields, collect data and upload data, and maintain a small fleet of various sensors and platforms needed for scientific collection. ACRE fields The flight area was a couple miles West of Purdue University, off of US-52 W. The flights were conducted over a series of both corn and soybean plots throughout the summer. Due to a plethora of conditions including weather and cloud coverage consistency, the flights were largely conducted on a day-to-day basis with the mindset of data collection quality over quantity. Soybean field on 6/7/24 The first couple weeks of data collection was monitoring growth rates of freshly germinated plants. To dem...
