NicoGIS is back. 🚀

GIS was the start. The map is much bigger now.

🌍 ArcGIS & Geospatial
💻 .NET & Software Architecture
☁️ Azure & Cloud
🤖 AI, LLMs & Agents
🧠 GeoAI & Spatial Data
Building and sharing across GIS, software, cloud & AI.
GIS is still at the core.

Geodatabase schema evolution is a dependency-graph problem, not a table editor.
Domains, subtypes, relationship classes and attribute rules constrain change order.
Diff the desired state, validate dependencies, then apply DDL deliberately.

🌍 GeoDynamics: exploring physics inside 3D GIS.

Rockfalls, barriers and water overtopping—combining ArcGIS Maps SDK for JavaScript, WebGL and Rapier physics.

Interactive geospatial simulations, built for the browser.

SqlClient Pool V2 uses Channels to open physical SQL connections concurrently.
But OpenAsync still runs blocking network I/O on worker threads: high RTT can move contention to the ThreadPool.
Measure cold-start latency, p99 and worker growth.
#dotnet #SQLServer

Embeddings are not magic black boxes. In ArcGIS Pro, SHAP over 256-D geodemographic embeddings can be aggregated by latent segments to reveal which geographic context drives predictions. Explainability should be part of GeoAI architecture, not an afterthought. #ArcGIS #GeoAI

[NicoGIS @nicogis]

Agent interoperability is becoming an application-layer concern. AG-UI gives .NET services a typed event stream for state, tool calls and lifecycle, while https://t.co/HM5KywiPmm keeps IChatClient as the boundary. Protocol first beats framework lock-in. #dotnet #AI

[NicoGIS @nicogis]

Agentic UI changes the Blazor architecture: the agent is no longer a chat box, but a stateful participant in the UI. Streamed content, tool calls, approvals and shared state become first-class components. The hard problem shifts from prompting to orchestration. #dotnet #AI

[NicoGIS @nicogis]

Spatial embeddings change GIS from “where is it?” to “what places are similar in context?”. In ArcGIS, geodemographic embeddings can feed clustering, prediction and similarity search without hand-crafting dozens of variables. Location becomes a learned feature. #ArcGIS #GeoAI

[NicoGIS @nicogis]

.NET 11 performance gains increasingly come from below application code: JIT optimizations, runtime-async, GC trimming/compaction and better codegen.
For architects, the rule is simple: benchmark on the target runtime, not on assumptions.
#dotnet #performance

[NicoGIS @nicogis]

Production LLMs are infrastructure systems, not just models. 🧠
Quantization changes VRAM pressure, throughput and latency. Batching changes GPU efficiency. HTTPS, observability and governance decide whether the deployment is actually production-ready.
#LLM #Azure

[NicoGIS @nicogis]

.NET performance isn’t just about faster code. ⚡

JIT, GC, allocations, SIMD, syscalls and locking all shape what happens at runtime.

With .NET 11, some of the most interesting improvements happen below your code.

Performance often starts where application code ends.
