Pushpin is an AI application service for parcel and land-lot change detection. It uses deep learning to analyze old and new high-resolution aerial imagery, enabling semi-automated parcel change detection and feature extraction. Its main use cases are county- or local-government property appraisal, tax assessment, and GIS review, helping users quickly identify changed parcels across large datasets.
According to the website copy, Pushpin does more than identify changes to primary structures: it flags all parcel-level changes and assigns one or more change types. Its classification system covers 10 categories: addition, construction, deck, demolished, flatwork, garage, new, other, pool, and shed. Technically, it uses a large training set labeled by mapping analysts from the assessment field. Inputs include parcel boundaries, older aerial imagery, and newer aerial imagery. The model is a custom CNN derived from ResNet50. Outputs include changed/unchanged judgments, change types, and geographic zones, making it easier to review results on desktop and prioritize tasks.
The official website provides relatively specific pricing: for projects with more than 100K parcels, the price is 25 cents per parcel, which Pushpin claims is 3x cheaper than competitors. In terms of delivery speed, Pushpin says county-scale projects involving hundreds of thousands of parcels can be completed within 4 weeks, which it claims is about 10x faster than competing offerings. The site provides Trial / Try for Free entry points, but does not specify the free quota, trial duration, or eligibility requirements.
Its strengths are a clearly defined vertical use case and a fairly complete workflow around aerial-imagery-based parcel change detection. The change categories are more granular than a simple binary classifier, making them better suited to government assessment and review workflows. The explicit pricing and turnaround-time commitments also make it easier to estimate costs for large-scale projects. The limitations are also clear: the main site does not provide quantitative metrics such as accuracy, recall, or false-positive rate; it does not explain API availability, GIS system integration, data formats, privacy compliance, or security mechanisms; and Chinese-language support is not mentioned.
Pushpin is better suited to county assessment offices, property tax assessment agencies, and GIS/aerial survey service providers in the United States or similar administrative systems, rather than as a general-purpose enterprise AI tool. Its accessibility from China is unknown, and supported payment methods are not disclosed. If using it in China, users should carefully confirm aerial imagery data sources, coordinate and parcel-boundary compatibility, local compliance requirements, network accessibility, and payment options. Alternative approaches include local remote-sensing interpretation services, GIS imagery change-detection services, or custom computer vision projects.
