Finding A Meaningful Model Esri

By Lauren Rosenshein, Lauren Scott, and Monica Pratt, Esri Figure 1: Mapping regression residuals from the model. Analyzing the residuals is an important step in finding a good model. The spatial statistics tools in ArcGIS let you address why questions using regression analysis. Regression models help answer questions like Regression analysis is used to understand, model, predict, and/or explain complex phenomena.

Because the spatial statistics tools used for regression analysis are part of the ArcGIS geoprocessing framework, they are well documented and accessed in a standard fashion. Figure 2: A portion of the diagnostics generated by OLS A deep learning model is a computer model that is trained using training samples and deep learning neural networks to perform various tasks such as object detection, pixel classification, detect changes, and objects classification. You can group deep learning models into three categories in ArcGIS: ArcGIS pretrained models automate the task of digitizing and extracting geographical features from imagery and point cloud datasets. Manually extracting features from raw data, such as digitizing footprints or generating land-cover maps, is time consuming.

Deep learning automates the process and minimizes the manual interaction necessary to complete these tasks. However, training a deep learning model can be complicated, as it requires large quantities of data, computing resources, and knowledge of deep learning. With ArcGIS pretrained models, you do not need to invest time and effort into training a deep learning model. The ArcGIS models have been trained on data from a variety of geographies. As new imagery becomes available to you, you can extract features and produce layers of GIS datasets for mapping, visualization, and analysis. The pretrained models are available on ArcGIS Living Atlas of the World if you have an ArcGIS account.

Pretrained deep learning models can instantly recognize complex shapes, patterns, and textures at various scales within images, point clouds, or video. This means that you can off-load tedious tasks of digitizing and extracting geographical features, such as roads, windows, and building footprints, with ease. With pretrained models, you no longer have to invest time and energy into labeling datasets and training your own model. Our pretrained models are trained on huge volumes of data from a variety of geographies to learn what to look for. Although our pretrained models aren't trained in all geographies, you can adapt them to your particular terrain, geography, and imagery type. Start with our models and then fine-tune the pretrained model to your needs using your labeled data.

Access a growing number of pretrained deep learning models from ArcGIS Living Atlas of the World. The imagery team works hard to continually train and deliver new, complementary models to support your business needs. ArcGIS Image for ArcGIS Online is required to run these models. This extension offers a secure, scalable, and performant cloud environment to perform your analysis. ArcGIS pretrained models automate the task of digitizing and extracting geographical features from imagery and point cloud datasets. Manually extracting features from raw data, such as digitizing footprints or generating land-cover maps, is time consuming.

However, training a deep learning model can be complicated, as it needs large quantities of data, computing resources, and knowledge of how deep learning works. With ArcGIS pretrained models, you do not need to invest time and effort into training a deep learning model. The ArcGIS models have been trained on data from a variety of geographies and work well across them. As new imagery becomes available to you, you can extract features and produce layers of GIS datasets for mapping, visualization, and analysis.

There are currently over 60 pretrained deep learning models in the ArcGIS Living Atlas of the World that can accelerate your geospatial workflows for image feature extraction and detection, pixel classification, object tracking, point... In this blog post, we will explore the benefits of using these ready-to-use pretrained models and how to start using them in the ArcGIS system. Artificial Intelligence (AI), machine learning, and deep learning (DL) are contributing to a more improved world in various ways. For instance, in agriculture, precision farming powered by AI technologies improves crop productivity, ensuring efficient resource allocation and maximizing yields.

In the field of law enforcement, predictive policing models driven by AI aid in combating crime proactively, identifying patterns and potential hotspots to prevent criminal activities. In the domain of weather forecasting and disaster management, the utilization of DL algorithms assists in accurately predicting severe weather events, thereby allowing necessary preparations to be made to mitigate their impact effectively. If you are new to the terms of AI, machine learning, and DL, I recommend reading this blog post first to learn how to differentiate between them. One area of AI where deep learning has performed exceedingly well is computer vision, or the ability for computers to see. We can use DL models in ArcGIS to perform tasks such as object detection, image classification, semantic (or pixel) classification, and instance segmentation (precise feature extraction). Figure 1 shows some of the most important computer vision tasks and how they can be applied to GIS.

Figure 1: Computer Vision tasks include image classification, pixel classification, object detection, and instance segmentation. Image classification involves assigning a single label or category to an entire image, such as determining whether an image represents a ‘damaged or ‘undamaged’ house. Pixel classification, in contrast, aims to label individual pixels within an image and is often used in tasks like land cover classification. Object detection goes a step further by identifying and localizing multiple objects within an image, such as detecting buildings or trees in aerial imagery. Lastly, instance segmentation involves not only detecting objects but also precisely delineating the boundaries of each instance, like identifying and outlining individual houses in satellite imagery. Each of these techniques serves a unique purpose in extracting valuable information from geographic and remotely sensed data.
