The use of computer vision has become increasingly important across a range of businesses in recent years. Geospatial analysis is one of the important fields where computer vision is used.
Thanks to technological advancements, we now have access to a vast amount of geospatial data, which can be used to train machine learning models to address practical issues.
This blog will cover seven of the most useful geospatial datasets that can be applied to computer vision projects. These datasets can be used in a variety of applications, including item detection, classification, and land cover mapping.
By the time this blog is out, you will understand the significance of these datasets and how you may use them in your computer vision applications.
What are Geospatial datasets?
Geospatial datasets are set of data that are linked to specific geographic spaces on the Earth's surface. These datasets include terrain, land cover, buildings, roads, rivers, and other physical environment variables and characteristics. Maps, satellite images, aerial pictures, and other spatial formats are frequently used to depict geospatial data.
Satellite photography, aerial surveys, GPS (Global Positioning System) measurements, remote sensing, and crowd-sourced data may all be used to create geospatial databases.
These datasets are useful for understanding and analyzing geographical patterns, making informed decisions, and building applications in areas like urban planning, environmental monitoring, transportation, agriculture, and disaster management.
Coordinates (latitude and longitude), elevation, land cover classifications, demographic data, and any other important information relating to specific geographic spaces can be included in the databases.
Geospatial datasets are increasingly being utilized in computer vision projects to train algorithms to comprehend and analyze images within a geographical context as computer vision and machine learning techniques develop.
Overall, geospatial datasets are critical resources for applications requiring location-based information such as geospatial analysis, mapping, visualization, and computer vision. They are critical for comprehending the Earth's surface and making educated decisions in a variety of disciplines.
Significance of GeoSpatial Datasets for Computer Vision Projects
Computer vision projects can benefit from the data that spatial datasets can offer. Here are a few causes for this:
1. Access to Geographic Context
For computer vision projects, geospatial datasets offer a spatial context. The information can aid in understanding the relationships between various characteristics in an image or a video. For instance, satellite imaging can reveal details about the geography of a region, the use of land, and the locations of objects on the ground.
2. Large-Scale Datasets
Large-scale geographic datasets frequently provide information on changes throughout time. Applications like tracking urban development, keeping tabs on environmental change, or comprehending transportation patterns can all benefit from this.
Geospatial datasets can also offer very exact information about an object's location, which is particularly helpful for applications like autonomous vehicles where precise location data is essential.
Geospatial datasets can be combined with other data sources, such as meteorological or demographic data, to offer a thorough picture of the environment.
All things considered, the usage of geographic datasets can improve the precision, effectiveness, and utility of computer vision projects, especially those pertaining to large-scale and spatially-oriented applications.
Top 7 GeoSpatial Datasets for Computer Vision Projects
Here are top 7 geospatial datasets that can help you in your machine vision projects are shown below:
A collaborative initiative called OpenStreetMap (OSM) gives anyone who wants to utilize its access to free geospatial data, including maps. The dataset is accessible in XML, JSON, and GeoJSON, among other formats. Various computer vision tasks, including object identification, image segmentation, and classification, can be accomplished with OSM.
SpaceNet is a dataset that provides high-resolution satellite imagery and labeled building footprints for machine learning research. The dataset covers areas of interest in multiple cities around the world, and it includes both RGB and multispectral imagery. SpaceNet can be used for a variety of computer vision projects, such as object detection, semantic segmentation, and change detection.
For the purposes of object detection, segmentation, and captioning, the dataset Common Objects in Context (COCO) offers labeled images. More than 2.5 million item instances are represented in the dataset's more than 330,000 photos and are labeled with bounding boxes, segmentation masks, and captions. Image identification, image captioning, and object tracking are just a few of the computer vision tasks for which COCO can be utilized.
For machine learning research, the dataset Cityscapes offers labeled images of urban street scenes. The collection includes high-resolution photographs of street scenes from 50 different cities and annotations for object detection, semantic segmentation, and instance segmentation. Computer vision tasks involving the detection of roads, lane markings, and traffic signs can all be carried out using cityscapes.
ImageNet is a sizable collection of images and annotations that have been extensively used in object and image recognition studies. More than 21,000 object types have been labeled with bounding boxes and segmentation masks across the dataset's more than 14 million photos. For a variety of computer vision tasks, such as object detection, image categorization, and scene comprehension, ImageNet can be employed.
6. Open Images
Over 9 million photos with object detection annotations make up the dataset known as Open Image. Numerous object categories, including humans, animals, automobiles, and home items, are represented in the dataset. Various computer vision tasks, including object detection, image segmentation, and classification, can be accomplished with Open Images.
7. Aerial Image Segmentation
The Aerial Image Segmentation dataset was made available by Kaggle for the purpose of segmenting satellite images. The dataset consists of a number of high-resolution satellite photos of different places annotated with the locations of numerous structures, roads, and water bodies. The dataset can be used for tasks like semantic segmentation, object detection, and classification in computer vision.
In conclusion, GeoSpatial datasets offer a multitude of data for computer vision projects, from street-level views to satellite photos. While COCO and ImageNet offer expansive item identification and recognition datasets, OpenStreetMap and SpaceNet offer extensive and varied geospatial data. Urban scene datasets for semantic segmentation and item detection are available from Cityscapes and Open Images.
Finally, the dataset for aerial image segmentation offers high-resolution satellite photos annotated with different items. These datasets offer a solid basis for creating and refining computer vision models that may glean insightful information from geographical data, making a positive impact on a variety of industries including urban planning, agriculture, and emergency response.
